| 1922 | Spiritual qualities only become advantageous with the growth of wisdom |
| 176 | Love follows beauty, wisdom is exceptionally beautiful, so love follows wisdom |
| 14179 | The finest branch of wisdom is justice and moderation in ordering states and families |
| 354 | Wisdom makes virtue and true goodness possible |
| 13786 | Wisdom is called 'beautiful', because it performs fine works |
| 291 | Don't assume that wisdom is the automatic consequence of old age |
| 13780 | Good people are no different from wise ones |
| 2136 | Philosophers become as divine and orderly as possible, by studying divinity and order |
| 3060 | Plato never mentions Democritus, and wished to burn his books |
| 13773 | For the truth you need Prodicus's fifty-drachma course, not his one-drachma course |
| 162 | Can we understand an individual soul without knowing the soul in general? |
| 326 | For relaxation one can consider the world of change, instead of eternal things |
| 160 | The highest ability in man is the ability to discuss unity and plurality in the nature of things |
| 1642 | We must fight fiercely for knowledge, understanding and intelligence |
| 315 | Philosophy is the supreme gift of the gods to mortals |
| 370 | Philosophy is a purification of the soul ready for the afterlife |
| 15447 | We shouldn't always follow where the argument leads! |
| 2056 | Philosophers are always switching direction to something more interesting |
| 125 | Is a gifted philosopher unmanly if he avoids the strife of the communal world? |
| 2083 | Either a syllable is its letters (making parts as knowable as whole) or it isn't (meaning it has no parts) |
| 166 | A speaker should be able to divide a subject, right down to the limits of divisibility |
| 16123 | Whenever you perceive a community of things, you should also hunt out differences in the group |
| 2086 | Understanding mainly involves knowing the elements, not their combinations |
| 1645 | The desire to split everything into its parts is unpleasant and unphilosophical |
| 224 | When questions are doubtful we should concentrate not on objects but on ideas of the intellect |
| 243 | It is foolish to quarrel with the mind's own reasoning processes |
| 350 | In investigation the body leads us astray, but the soul gets a clear view of the facts |
| 241 | We ought to follow where the argument leads us |
| 2082 | A rational account is essentially a weaving together of things with names |
| 362 | The greatest misfortune for a person is to develop a dislike for argument |
| 306 | Nothing can come to be without a cause |
| 192 | Only one thing can be contrary to something |
| 232 | Opposites are as unlike as possible |
| 13778 | A dialectician is someone who knows how to ask and to answer questions |
| 2151 | Dialectic is the only method of inquiry which uproots the things which it takes for granted |
| 2154 | The ability to take an overview is the distinguishing mark of a dialectician |
| 4011 | For Plato, rationality is a vision of and love of a cosmic rational order |
| 287 | Good analysis involves dividing things into appropriate forms without confusion |
| 1644 | Dialectic should only be taught to those who already philosophise well |
| 1654 | In "Gorgias" Socrates is confident that his 'elenchus' will decide moral truth |
| 4321 | We should test one another, by asking and answering questions |
| 2093 | You must never go against what you actually believe |
| 2130 | People often merely practice eristic instead of dialectic, because they don't analyse the subject-matter |
| 2052 | Eristic discussion is aggressive, but dialectic aims to help one's companions in discussion |
| 16124 | No one want to define 'weaving' just for the sake of weaving |
| 16125 | To reveal a nature, divide down, and strip away what it has in common with other things |
| 15854 | A primary element has only a name, and no logos, but complexes have an account, by weaving the names |
| 251 | Truth heads the list of all things good, for gods and men alike |
| 13776 | Truths say of what is that it is, falsehoods say of what is that it is not |
| 2145 | In mathematics certain things have to be accepted without further explanation |
| 15845 | It seems absurd that seeing a person's limbs, the one is many, and yet the many are one |
| 13777 | A name is a sort of tool |
| 13790 | A name-giver might misname something, then force other names to conform to it |
| 13791 | Things must be known before they are named, so it can't be the names that give us knowledge |
| 13789 | Anyone who knows a thing's name also knows the thing |
| 11259 | How can you seek knowledge of something if you don't know it? |
| 13155 | If you add one to one, which one becomes two, or do they both become two? |
| 9865 | Daily arithmetic counts unequal things, but pure arithmetic equalises them |
| 8726 | Geometry can lead the mind upwards to truth and philosophy |
| 9867 | It is absurd to define a circle, but not be able to recognise a real one |
| 9863 | We aim for elevated discussion of pure numbers, not attaching them to physical objects |
| 9864 | In pure numbers, all ones are equal, with no internal parts |
| 8727 | Geometry is not an activity, but the study of unchanging knowledge |
| 10216 | We master arithmetic by knowing all the numbers in our soul |
| 16150 | One is, so numbers exist, so endless numbers exist, and each one must partake of being |
| 9861 | The same thing is both one and an unlimited number at the same time |
| 324 | Before the existence of the world there must have been being, space and becoming |
| 9862 | To become rational, philosophers must rise from becoming into being |
| 229 | The one was and is and will be and was becoming and is becoming and will become |
| 11278 | What does 'that which is not' refer to? |
| 1643 | If statements about non-existence are logically puzzling, so are statements about existence |
| 2062 | The only movement possible for the One is in space or in alteration |
| 7022 | To be is to have a capacity, to act on other things, or to receive actions |
| 2061 | The best things (gods, healthy bodies, good souls) are least liable to change |
| 2063 | How can beauty have identity if it changes? |
| 2060 | There seem to be two sorts of change: alteration and motion |
| 15857 | Any mixture which lacks measure and proportion doesn't even count as a mixture at all |
| 14503 | If a mixture does not contain measure and proportion, it is corrupted and destroyed |
| 7953 | Reasoning needs to cut nature accurately at the joints |
| 221 | Absolute ideas, such as the Good and the Beautiful, cannot be known by us |
| 6562 | Plato's reality has unchanging Parmenidean forms, and Heraclitean flux |
| 1641 | Some alarming thinkers think that only things which you can touch exist |
| 10784 | Whenever there's speech it has to be about something |
| 13775 | We only succeed in cutting if we use appropriate tools, not if we approach it randomly |
| 16121 | I revere anyone who can discern a single thing that encompasses many things |
| 14502 | Plato's idea of 'structure' tends to be mathematically expressed |
| 223 | If you deny that each thing always stays the same, you destroy the possibility of discussion |
| 227 | You must always mean the same thing when you utter the same name |
| 153 | It takes a person to understand, by using universals, and by using reason to create a unity out of sense-impressions |
| 2142 | The plurality of beautiful things must belong to a single class, because they have a single particular character |
| 219 | If absolute ideas existed in us, they would cease to be absolute |
| 220 | The concept of a master includes the concept of a slave |
| 2159 | Craftsmen making furniture refer to the form, but no one manufactures the form of furniture |
| 154 | We would have an overpowering love of knowledge if we had a pure idea of it - as with the other Forms |
| 210 | It would absurd to think there were abstract Forms for vile things like hair, mud and dirt |
| 16151 | Plato moves from Forms to a theory of genera and principles in his later work |
| 17948 | Plato's Forms meant that the sophists only taught the appearance of wisdom and virtue |
| 3039 | When Diogenes said he could only see objects but not their forms, Plato said it was because he had eyes but no intellect |
| 228 | Greatness and smallness must exist, to be opposed to one another, and come into being in things |
| 12043 | Forms are not universals, as they don't cover every general term |
| 16122 | Good thinkers spot forms spread through things, or included within some larger form |
| 10422 | The not-beautiful is part of the beautiful, though opposed to it, and is just as real |
| 12042 | Plato's Forms were seen as part of physics, rather than of metaphysics |
| 307 | Something will always be well-made if the maker keeps in mind the eternal underlying pattern |
| 318 | In addition to the underlying unchanging model and a changing copy of it, there must also be a foundation of all change |
| 1607 | Diotima said the Forms are the objects of desire in philosophical discourse |
| 360 | We must have a prior knowledge of equality, if we see 'equal' things and realise they fall short of it |
| 321 | For knowledge and true opinion to be different there must be Forms; otherwise we are just stuck with sensations |
| 211 | If admirable things have Forms, maybe everything else does as well |
| 317 | The universe is basically an intelligible and unchanging model, and a visible and changing copy of it |
| 215 | If things partake of ideas, this implies either that everything thinks, or that everything actually is thought |
| 17 | A Form applies to a set of particular things with the same name |
| 212 | The whole idea of each Form must be found in each thing which participates in it |
| 218 | Participation is not by means of similarity, so we are looking for some other method of participation |
| 368 | Other things are named after the Forms because they participate in them |
| 213 | Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once |
| 1 | There is only one source for all beauty |
| 304 | Beautiful things must be different from beauty itself, but beauty itself must be present in each of them |
| 4447 | If the good is one, is it unchanged when it is in particulars, and is it then separated from itself? |
| 556 | If there is one Form for both the Form and its participants, they must have something in common |
| 216 | If things are made alike by participating in something, that thing will be the absolute idea |
| 190 | If asked whether justice itself is just or unjust, you would have to say that it is just |
| 563 | If gods are like men, they are just eternal men; similarly, Forms must differ from particulars |
| 214 | If absolute greatness and great things are seen as the same, another thing appears which makes them seem great |
| 217 | Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) |
| 557 | A Form is a cause of things only in the way that white mixed with white is a cause |
| 565 | The Forms cannot be changeless if they are in changing things |
| 13263 | We can grasp whole things in science, because they have a mathematics and a teleology |
| 13787 | Doesn't each thing have an essence, just as it has other qualities? |
| 15855 | If we see everything as separate, we can then give no account of it |
| 13261 | Plato sees an object's structure as expressible in mathematics |
| 13265 | Plato was less concerned than Aristotle with the source of unity in a complex object |
| 15851 | Parts must belong to a created thing with a distinct form |
| 15856 | A thing can become one or many, depending on how we talk about it |
| 593 | Plato's holds that there are three substances: Forms, mathematical entities, and perceptible bodies |
| 15846 | In Parmenides, if composition is identity, a whole is nothing more than its parts |
| 374 | If one object is divided into its parts, someone can then say that one are many and many is one |
| 2084 | If a word has no parts and has a single identity, it turns out to be the same kind of thing as a letter |
| 15849 | Plato says only a one has parts, and a many does not |
| 15850 | Anything which has parts must be one thing, and parts are of a one, not of a many |
| 15843 | The whole can't be the parts, because it would be all of the parts, which is the whole |
| 13260 | Plato says wholes are either containers, or they're atomic, or they don't exist |
| 13259 | It seems that the One must be composed of parts, which contradicts its being one |
| 15844 | A sum is that from which nothing is lacking, which is a whole |
| 11237 | Only universals have essence |
| 13774 | Things don't have every attribute, and essence isn't private, so each thing has an essence |
| 11238 | Plato and Aristotle take essence to make a thing what it is |
| 13772 | Is the being or essence of each thing private to each person? |
| 16516 | The ship which Theseus took to Crete is now sent to Delos crowned with flowers |
| 15847 | Two things relate either as same or different, or part of a whole, or the whole of the part |
| 13788 | If we made a perfect duplicate of Cratylus, there would be two Cratyluses |
| 2133 | Knowledge must be of the permanent unchanging nature of things |
| 2080 | Things are only knowable if a rational account (logos) is possible |
| 16120 | Knowing how to achieve immortality is pointless without the knowledge how to use immortality |
| 16126 | Expertise is knowledge of the whole by means of the parts |
| 20184 | The only real evil is loss of knowledge |
| 20185 | The most important things in life are wisdom and knowledge |
| 20219 | True opinions only become really valuable when they are tied down by reasons |
| 2050 | It is impossible to believe something which is held to be false |
| 2076 | How can a belief exist if its object doesn't exist? |
| 389 | How can you be certain about aspects of the world if they aren't constant? |
| 357 | People are obviously recollecting when they react to a geometrical diagram |
| 5961 | The soul gets its goodness from god, and its evil from previous existence. |
| 359 | If we feel the inadequacy of a resemblance, we must recollect the original |
| 5985 | Seeking and learning are just recollection |
| 9343 | To achieve pure knowledge, we must get rid of the body and contemplate things with the soul |
| 2045 | Perception is infallible, suggesting that it is knowledge |
| 2067 | Our senses could have been separate, but they converge on one mind |
| 2069 | Thought must grasp being itself before truth becomes possible |
| 2078 | You might mistake eleven for twelve in your senses, but not in your mind |
| 2162 | If theory and practice conflict, the best part of the mind accepts theory, so the other part is of lower grade |
| 151 | True knowledge is of the reality behind sense experience |
| 1637 | A soul without understanding is ugly |
| 334 | Only bird-brained people think astronomy is entirely a matter of evidence |
| 2068 | With what physical faculty do we perceive pairs of opposed abstract qualities? |
| 1923 | As a guide to action, true opinion is as good as knowledge |
| 174 | True opinion without reason is midway between wisdom and ignorance |
| 2140 | True belief without knowledge is like blind people on the right road |
| 2089 | An inadequate rational account would still not justify knowledge |
| 2085 | Parts and wholes are either equally knowable or equally unknowable |
| 2091 | Without distinguishing marks, how do I know what my beliefs are about? |
| 2090 | A rational account involves giving an image, or analysis, or giving a differentiating mark |
| 2087 | A rational account might be seeing an image of one's belief, like a reflection in a mirror |
| 2081 | Maybe primary elements can be named, but not receive a rational account |
| 2088 | A rational account of a wagon would mean knowledge of its hundred parts |
| 303 | Say how many teeth the other has, then count them. If you are right, we will trust your other claims |
| 13792 | There can't be any knowledge if things are constantly changing |
| 2047 | What evidence can be brought to show whether we are dreaming or not? |
| 1919 | You don't need to learn what you know, and how do you seek for what you don't know? |
| 335 | Do the gods also hold different opinions about what is right and honourable? |
| 2053 | If you claim that all beliefs are true, that includes beliefs opposed to your own |
| 2054 | Clearly some people are superior to others when it comes to medicine |
| 2059 | How can a relativist form opinions about what will happen in the future? |
| 165 | If the apparent facts strongly conflict with probability, it is in everyone's interests to suppress the facts |
| 17085 | A good explanation totally rules out the opposite explanation (so Forms are required) |
| 15859 | To investigate the causes of things, study what is best for them |
| 2096 | Is the function of the mind management, authority and planning - or is it one's whole way of life? |
| 9296 | The soul is self-motion |
| 13781 | Soul causes the body to live, and gives it power to breathe and to be revitalized |
| 6009 | Psychic conflict is clear if appetite is close to the body and reason fairly separate |
| 6041 | There is a third element to the mind - spirit - lying between reason and appetite |
| 5962 | Plato says the soul is ordered by number |
| 2127 | The mind has parts, because we have inner conflicts |
| 1737 | The soul seems to have an infinity of parts |
| 13154 | Do we think and experience with blood, air or fire, or could it be our brain? |
| 191 | Everything resembles everything else up to a point |
| 364 | One soul can't be more or less of a soul than another |
| 181 | Only the gods stay unchanged; we replace our losses with similar acquisitions |
| 180 | We call a person the same throughout life, but all their attributes change |
| 330 | No one wants to be bad, but bad men result from physical and educational failures, which they do not want or choose |
| 282 | Non-physical beauty can only be shown clearly by speech |
| 116 | Rhetoric is irrational about its means and its ends |
| 159 | Only a good philosopher can be a good speaker |
| 5946 | 'Phaedrus' pioneers the notion of philosophical rhetoric |
| 5945 | The 'Republic' is a great work of rhetorical theory |
| 158 | An excellent speech seems to imply a knowledge of the truth in the mind of the speaker |
| 114 | Rhetoric can produce conviction, but not educate people about right and wrong |
| 3324 | Plato's whole philosophy may be based on being duped by reification - a figure of speech |
| 283 | The question of whether or not to persuade comes before the science of persuasion |
| 16 | We avoid evil either through a natural aversion, or because we have acquired knowledge |
| 1655 | If goodness needs true opinion but not knowledge, you can skip the 'examined life' |
| 202 | No one willingly and knowingly embraces evil |
| 203 | Courage is knowing what should or shouldn't be feared |
| 173 | Beauty and goodness are the same |
| 184 | Progress goes from physical beauty, to moral beauty, to the beauty of knowledge, and reaches absolute beauty |
| 390 | If goodness involves moderation and proportion, then it seems to be found in beauty |
| 183 | Stage two is the realisation that beauty of soul is of more value than beauty of body |
| 4026 | Beauty is harmony with what is divine, and ugliness is lack of such harmony |
| 172 | Love of ugliness is impossible |
| 297 | What is fine is the parent of goodness |
| 299 | What is fine is always difficult |
| 155 | Beauty is the clearest and most lovely of the Forms |
| 249 | People who value beauty above virtue insult the soul by placing the body above it |
| 284 | A soul which lacks understanding is ugly |
| 2160 | Representation is two steps removed from the truth |
| 2135 | Truth is closely related to proportion |
| 2163 | Artists should be excluded from a law-abiding community, because they destroy the rational mind |
| 171 | Music is a knowledge of love in the realm of harmony and rhythm |
| 316 | Music has harmony like the soul, and serves to reorder disharmony within us |
| 16565 | Without the surface decoration, poetry shows only appearances and nothing of what is real |
| 193 | Some things are good even though they are not beneficial to men |
| 9274 | Plato's legacy to European thought was the Good, the Beautiful and the True |
| 301 | Only knowledge of some sort is good |
| 137 | As with other things, a good state is organised and orderly |
| 94 | Pleasure is better with the addition of intelligence, so pleasure is not the good |
| 2138 | Pleasure is commonly thought to be the good, though the more ingenious prefer knowledge |
| 393 | Good first, then beauty, then reason, then knowledge, then pleasure |
| 2143 | Good has the same role in the world of knowledge as the sun has in the physical world |
| 2144 | Goodness makes truth and knowledge possible |
| 2164 | Bad is always destructive, where good preserves and benefits |
| 391 | The good involves beauty, proportion and truth |
| 295 | The good is beautiful |
| 135 | All activity aims at the good |
| 136 | Good should be the aim of pleasant activity, not the other way round |
| 4007 | For Plato we abandon honour and pleasure once we see the Good |
| 2139 | Every person, and every activity, aims at the good |
| 2137 | The main aim is to understand goodness, which gives everything its value and advantage |
| 2141 | I suggest that we forget about trying to define goodness itself for the time being |
| 2147 | The sight of goodness leads to all that is fine and true and right |
| 392 | Neither intellect nor pleasure are the good, because they are not perfect and self-sufficient |
| 14178 | Happiness is secure enjoyment of what is good and beautiful |
| 332 | One should exercise both the mind and the body, to avoid imbalance |
| 17947 | Plato decided that the virtuous and happy life was the philosophical life |
| 139 | A good person is bound to act well, and this brings happiness |
| 177 | If a person is good they will automatically become happy |
| 385 | Some of the pleasures and pains we feel are false |
| 132 | If happiness is the satisfaction of desires, then a life of scratching itches should be happiness |
| 200 | People tend only to disapprove of pleasure if it leads to pain, or prevents future pleasure |
| 371 | Reason, memory, truth and wisdom are far better than pleasure, for those who can attain them |
| 379 | The good must be sufficient and perfect, and neither intellect nor pleasure are that |
| 373 | Pleasure is certainly very pleasant, but it doesn't follow that all pleasures are good |
| 382 | It is unlikely that the gods feel either pleasure or pain |
| 240 | It would be strange if the gods rewarded those who experienced the most pleasure in life |
| 264 | The conquest of pleasure is the noblest victory of all |
| 157 | Most pleasure is release from pain, and is therefore not worthwhile |
| 376 | Would you prefer a life of pleasure without reason, or one of reason without pleasure? |
| 4322 | In slaking our thirst the goodness of the action and the pleasure are clearly separate |
| 2134 | Philosophers are concerned with totally non-physical pleasures |
| 2070 | Even people who think pleasure is the good admit that there are bad pleasures |
| 197 | Some pleasures are not good, and some pains are not evil |
| 2156 | There are three types of pleasure, for reason, for spirit and for appetite |
| 387 | A small pure pleasure is much finer than a large one contaminated with pain |
| 2157 | Nice smells are intensive, have no preceding pain, and no bad after-effect |
| 381 | We feel pleasure when we approach our natural state of harmony |
| 134 | Good and bad people seem to experience equal amounts of pleasure and pain |
| 361 | It is a mistake to think that the most violent pleasure or pain is therefore the truest reality |
| 386 | Intense pleasure and pain are not felt in a good body, but in a worthless one |
| 328 | Everything that takes place naturally is pleasant |
| 4319 | In a fool's mind desire is like a leaky jar, insatiable in its desires, and order and contentment are better |
| 2123 | Excessive pleasure deranges people, making the other virtues impossible |
| 2158 | Pleasure-seekers desperately seek illusory satisfaction, like filling a leaky vessel |
| 1590 | The just man does not harm his enemies, but benefits everyone |
| 14177 | Love assists men in achieving merit and happiness |
| 179 | Love is desire for perpetual possession of the good |
| 128 | Is it natural to simply indulge our selfish desires? |
| 12 | If we were invisible, would the just man become like the unjust? |
| 2168 | Clever criminals do well at first, but not in the long run |
| 302 | What knowledge is required to live well? |
| 122 | Moral rules are made by the weak members of humanity |
| 2173 | As religion and convention collapsed, Plato sought morals not just in knowledge, but in the soul |
| 5 | Justice is merely the interests of the stronger party |
| 4547 | Plato measured the degree of reality by the degree of value |
| 143 | The two ruling human principles are the natural desire for pleasure, and an acquired love of virtue |
| 7503 | Plato never refers to examining the conscience |
| 265 | An action is only just if it is performed by someone with a just character and outlook |
| 269 | Attempted murder is like real murder, but we should respect the luck which avoided total ruin |
| 2166 | We should behave well even if invisible, for the health of the mind |
| 1636 | Wickedness is an illness of the soul |
| 378 | A life of pure pleasure with no intellect is the life of a jellyfish |
| 388 | Hedonists must say that someone in pain is bad, even if they are virtuous |
| 130 | Is the happiest state one of sensual, self-indulgent freedom? |
| 377 | If you lived a life of maximum pleasure, would you still be lacking anything? |
| 19946 | Morality is a compromise, showing restraint, to avoid suffering wrong without compensation |
| 2097 | Isn't it better to have a reputation for goodness than to actually be good? |
| 7 | Surely you don't return a borrowed weapon to a mad friend? |
| 8 | Is right just the interests of the powerful? |
| 15 | Sin first, then sacrifice to the gods from the proceeds |
| 13785 | 'Arete' signifies lack of complexity and a free-flowing soul |
| 6015 | Plato, unusually, said that theoretical and practical wisdom are inseparable |
| 2095 | If something has a function then it has a state of being good |
| 182 | The first step on the right path is the contemplation of physical beauty when young |
| 13 | Is the supreme reward for virtue to be drunk for eternity? |
| 5944 | For Plato, virtue is its own reward |
| 144 | Reason impels us towards excellence, which teaches us self-control |
| 4332 | Virtue is a concord of reason and emotion, with pleasure and pain trained to correct ends |
| 248 | A serious desire for moral excellence is very rare indeed |
| 253 | Every crime is the result of excessive self-love |
| 263 | The only worthwhile life is one devoted to physical and moral perfection |
| 170 | The only slavery which is not dishonourable is slavery to excellence |
| 120 | Should we avoid evil because it will bring us bad consequences? |
| 235 | Virtue is the aim of all laws |
| 1913 | Is virtue taught, or achieved by practice, or a natural aptitude, or what? |
| 1921 | If virtue is a type of knowledge then it ought to be taught |
| 1927 | It seems that virtue is neither natural nor taught, but is a divine gift |
| 188 | Socrates did not believe that virtue could be taught |
| 189 | If we punish wrong-doers, it shows that we believe virtue can be taught |
| 205 | Protagoras contradicts himself by saying virtue is teachable, but then that it is not knowledge |
| 204 | Socrates is contradicting himself in claiming virtue can't be taught, but that it is knowledge |
| 118 | I would rather be a victim of crime than a criminal |
| 305 | Something which lies midway between two evils is better than either of them |
| 281 | The arts produce good and beautiful things by preserving the mean |
| 2129 | Goodness is mental health, badness is mental sickness |
| 277 | The Guardians must aim to discover the common element in the four cardinal virtues |
| 1916 | Even if virtues are many and various, they must have something in common to make them virtues |
| 1918 | How can you know part of virtue without knowing the whole? |
| 2155 | True goodness requires mental unity and harmony |
| 2126 | A good community necessarily has wisdom, courage, self-discipline and morality |
| 254 | Excessive laughter and tears must be avoided |
| 131 | If absence of desire is happiness, then nothing is happier than a stone or a corpse |
| 140 | Self-indulgent desire makes friendship impossible, because it makes a person incapable of co-operation |
| 129 | Do most people praise self-discipline and justice because they are too timid to gain their own pleasure? |
| 2092 | Simonides said morality is helping one's friends and harming one's enemies |
| 259 | Justice is granting the equality which unequals deserve |
| 266 | Injustice is the mastery of the soul by bad feelings, even if they do not lead to harm |
| 119 | A criminal is worse off if he avoids punishment |
| 293 | Being unafraid (perhaps through ignorance) and being brave are two different things |
| 4320 | The popular view is that health is first, good looks second, and honest wealth third |
| 351 | War aims at the acquisition of wealth, because we are enslaved to the body |
| 256 | Virtue and great wealth are quite incompatible |
| 242 | The best people are produced where there is no excess of wealth or poverty |
| 156 | Bad people are never really friends with one another |
| 294 | People say that friendship exists only between good men |
| 298 | While sex is very pleasant, it should be in secret, as it looks contemptible |
| 19889 | People need society because the individual has too many needs |
| 19890 | All exchanges in a community are for mutual benefit |
| 10 | After a taste of mutual harm, men make a legal contract to avoid it |
| 245 | Totalitarian states destroy friendships and community spirit |
| 2132 | Only rule by philosophers of integrity can keep a community healthy |
| 2149 | Reluctant rulers make a better and more unified administration |
| 141 | A good citizen won't be passive, but will redirect the needs of the state |
| 2131 | Is there anything better for a community than to produce excellent people? |
| 239 | Education in virtue produces citizens who are active but obedient |
| 236 | Sound laws achieve the happiness of those who observe them |
| 262 | Men and women should qualify equally for honours on merit |
| 123 | Do most people like equality because they are second-rate? |
| 1402 | Friendship is impossible between master and slave, even if they are made equal |
| 124 | Does nature imply that it is right for better people to have greater benefits? |
| 2148 | To gain knowledge, turn away from the world of change, and focus on true goodness |
| 260 | Control of education is the key office of state, and should go to the best citizen |
| 2152 | Dialectic is the highest and most important part of the curriculum |
| 257 | Mathematics has the widest application of any subject on the curriculum |
| 238 | Children's games should channel their pleasures into adult activity |
| 331 | Bad governments prevent discussion, and discourage the study of virtue |
| 322 | Intelligence is the result of rational teaching; true opinion can result from irrational persuasion |
| 2153 | Compulsory intellectual work never remains in the mind |
| 222 | Only a great person can understand the essence of things, and an even greater person can teach it |
| 1638 | Didactic education is hard work and achieves little |
| 4331 | Education is channelling a child's feelings into the right course before it understands why |
| 250 | The best way to educate the young is not to rebuke them, but to set a good example |
| 310 | The creator of the cosmos had no envy, and so wanted things to be as like himself as possible |
| 311 | The cosmos must be unique, because it resembles the creator, who is unique |
| 275 | Creation is not for you; you exist for the sake of creation |
| 2094 | A thing's function is what it alone can do, or what it does better than other things |
| 233 | Some things do not partake of the One |
| 231 | Everything partakes of the One in some way |
| 225 | The unlimited has no shape and is endless |
| 312 | Time came into existence with the heavens, so that there will be a time when they can be dissolved |
| 314 | Heavenly movements gave us the idea of time, and caused us to inquire about the heavens |
| 327 | There are two types of cause, the necessary and the divine |
| 13156 | Fancy being unable to distinguish a cause from its necessary background conditions! |
| 325 | We must consider the four basic shapes as too small to see, only becoming visible in large numbers |
| 13779 | The natural offspring of a lion is called a 'lion' (but what about the offspring of a king?) |
| 309 | Clearly the world is good, so its maker must have been concerned with the eternal, not with change |
| 369 | If the Earth is spherical and in the centre, it is kept in place by universal symmetry, not by force |
| 148 | If the prime origin is destroyed, it will not come into being again out of anything |
| 308 | If the cosmos is an object of perception then it must be continually changing |
| 273 | Movement is transmitted through everything, and it must have started with self-generated motion |
| 279 | Only divine things can always stay the same, and bodies are not like that |
| 13783 | Even the gods love play |
| 175 | Gods are not lovers of wisdom, because they are already wise |
| 152 | The mind of God is fully satisfied and happy with a vision of reality and truth |
| 337 | It seems that the gods love things because they are pious, rather than making them pious by loving them |
| 336 | Is what is pious loved by the gods because it is pious, or is it pious because they love it? (the 'Euthyphro Question') |
| 2058 | God must be the epitome of goodness, and we can only approach a divine state by being as good as possible |
| 8004 | In 'The Laws', to obey the law is to be obey god |
| 150 | We cannot conceive of God, so we have to think of Him as an immortal version of ourselves |
| 234 | We couldn't discuss the non-existence of the One without knowledge of it |
| 1423 | Self-movers are clearly superior to things moved, so they must initiate all movement |
| 1424 | There must be a soul to originate movement, which is presumably the soul that originates good rather than evil |
| 1426 | The motion of the sun is from a soul within it, or a soul touching it, or a supernatural force |
| 274 | Soul must be the cause of all the opposites, such as good and evil or beauty and ugliness |
| 1425 | The universe is ordered and moves in perfect circles, showing that a good soul originated it |
| 14 | If the gods are non-existent or indifferent, why bother to deceive them? |
| 278 | If astronomical movements are seen as necessary instead of by divine will, this leads to atheism |
| 149 | There isn't a single reason for positing the existence of immortal beings |
| 363 | Whether the soul pre-exists our body depends on whether it contains the ultimate standard of reality |
| 146 | Soul is always in motion, so it must be self-moving and immortal |
| 2165 | Something is unlikely to be immortal if it is imperfectly made from diverse parts |
| 2057 | There must always be some force of evil ranged against good |
| 2120 | God is responsible for the good things, but we must look elsewhere for the cause of the bad things |
