8093 | Seek wisdom rather than truth; it is easier [Joubert] |
Full Idea: To seek wisdom rather than truth. It is more within our grasp. | |
From: Joseph Joubert (Notebooks [1800], 1797) | |
A reaction: A nice challenge to the traditional goal of philosophy. The idea that we should 'seek truth' only seems to have emerged during the Reformation. The Greeks may well never have dreamed of such a thing. |
8095 | We must think with our entire body and soul [Joubert] |
Full Idea: Everything we think must be thought with our entire being, body and soul. | |
From: Joseph Joubert (Notebooks [1800], 1798) | |
A reaction: Not just that thinking must be a whole-hearted activity, but that the very contents of our thinking will be better if it arises out of being a physical creature, and not just a disembodied reasoner. Maybe the bowels are not needed to analyse set theory. |
8107 | The love of certainty holds us back in metaphysics [Joubert] |
Full Idea: What stops or holds us back in metaphysics is a love of certainty. | |
From: Joseph Joubert (Notebooks [1800], 1814) | |
A reaction: This is a prominent truth from the age of Descartes, but may have diminished in the twenty-first century. The very best metaphysicians (e.g. Aristotle and Lewis) always end in a trail of dots when things become unsure. |
23657 | The existence of tensed verbs shows that not all truths are necessary truths [Reid] |
Full Idea: If all truths were necessary truths, there would be no occasion for different tenses in the verbs by which they are expressed. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 5) | |
A reaction: This really is like modern linguistic analysis. Of course the tensed verbs might only indicate times when the universal necessities have been noticed by speakers. …But then the noticing would be contingent! |
8099 | The truths of reason instruct, but they do not illuminate [Joubert] |
Full Idea: There are truths that instruct, perhaps, but they do not illuminate. In this class are all the truths of reasoning. | |
From: Joseph Joubert (Notebooks [1800], 1800) | |
A reaction: A rather romantic view, which strikes me as false. An inspiring truth can suddenly collapse when you see why it must be false. Equally a line of reasoning can lead to a truth which need becomes an illumination. |
23655 | An ad hominem argument is good, if it is shown that the man's principles are inconsistent [Reid] |
Full Idea: It is a good argument ad hominem, if it can be shewn that a first principle which a man rejects, stands upon the same footing with others which he admits, …for he must then be guilty of an inconsistency. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 4) | |
A reaction: Good point. You can't divorce 'pure' reason from the reasoners, because the inconsistency of two propositions only matters when they are both asserted together. …But attacking the ideas isn't quite the same as attacking the person. |
8098 | Truth consists of having the same idea about something that God has [Joubert] |
Full Idea: Truth consists of having the same idea about something that God has. | |
From: Joseph Joubert (Notebooks [1800], 1800) | |
A reaction: Presumably sceptics about the existence of objective truth must also be sceptical about the possibility of such a God. I think Joubert is close to the nature of truth here. It is a remote and barely imaginable ideal. |
23659 | If someone denies that he is thinking when he is conscious of it, we can only laugh [Reid] |
Full Idea: If any man could be found so frantic as to deny that he thinks, while he is conscious of it, I may wonder, I may laugh, or I may pity him, but I cannot reason the matter with him. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 5) | |
A reaction: An example of the influence of Descartes' Cogito running through all subsequent European philosophy. There remain the usual questions about personal identity which then arise, but Reid addresses those. |
23662 | The existence of ideas is no more obvious than the existence of external objects [Reid] |
Full Idea: If external objects be perceived immediately, we have the same reason to believe their existence as philosophers have to believe the existence of ideas. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 5) | |
A reaction: He doesn't pay much attention to mirages and delusions, but in difficult conditions of perception we are confident of our experiences but doubtful about the objects they represent. |
23661 | We are only aware of other beings through our senses; without that, we are alone in the universe [Reid] |
Full Idea: We can have no communication, no correspondence or society with any created being, but by means of our senses. And, until we rely on their testimony, we must consider ourselves as being alone in the universe. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 5) | |
A reaction: I'm not aware of any thinker before this so directly addressing solipsism. Even the champion of direct and common sense realism has to recognise the intermediary of our senses when accepting other minds. |
23654 | In obscure matters the few must lead the many, but the many usually lead in common sense [Reid] |
Full Idea: In matters beyond the reach of common understanding, the many are led by the few, and willingly yield to their authority. But, in matters of common sense, the few must yield to the many, when local and temporary prejudices are removed. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 4) | |
A reaction: Wishful thinking in the 21st century, when the many routinely deny the authority of the expert few, and the expert few occasionally prove that the collective common sense of the many is delusional. I still sort of agree with Reid. |
23660 | The theory of ideas, popular with philosophers, means past existence has to be proved [Reid] |
Full Idea: The theory concerning ideas, so generally received by philosophers, destroys all the authority of memory. …This theory made it necessary for them to find out arguments to prove the existence of external objects …and of things past. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 5) | |
A reaction: Reid was a very articulate direct realist. He seems less aware than the rest of us of the problem of delusions and false memories. Our strong sense that immediate memories are reliable is certainly inexplicable. |
8101 | To know is to see inside oneself [Joubert] |
Full Idea: To know: it is to see inside oneself. | |
From: Joseph Joubert (Notebooks [1800], 1800) | |
A reaction: Extreme internalism about justification! Personally I am becoming convinced that 'know' (unlike 'believe' and 'true') is an entirely social concept. Fools spend a lot of time instrospecting; wise people ask around, and check in books. |
23658 | Consciousness is an indefinable and unique operation [Reid] |
Full Idea: Consciousness is an operation of the understanding of its own kind, and cannot be logically defined. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 5) | |
A reaction: It is interesting that has tried to define consciousness, rather than just assuming it. I note that he calls consciousness an 'operation', rather than an entity. Good. |
8094 | The imagination has made more discoveries than the eye [Joubert] |
Full Idea: The imagination has made more discoveries than the eye. | |
From: Joseph Joubert (Notebooks [1800], 1797) | |
A reaction: As a fan of the imagination, I love this one. I suspect that imagination, which was marginalised by Descartes, is actually the single most important aspect of thought (in slugs as well as humans). Abstraction requires imagination. |
8103 | A thought is as real as a cannon ball [Joubert] |
Full Idea: A thought is a thing as real as a cannon ball. | |
From: Joseph Joubert (Notebooks [1800], 1801) | |
A reaction: Nice. The realisation of a thought can strike someone as if they have been assaulted, and hearing some remarks can be as bad as being stabbed. That is quite apart from political consequences. Joubert is good on the physicality of thinking. |
23656 | The structure of languages reveals a uniformity in basic human opinions [Reid] |
Full Idea: What is common in the structure of languages, indicates an uniformity of opinion in those things upon which that structure is grounded. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 4) | |
A reaction: Reid was more interested than his contemporaries in the role of language in philosophy. The first idea sounds like Chomsky. I would add to this that the uniformity of common opinion reflects uniformities in the world they are talking about. |
8100 | Where does the bird's idea of a nest come from? [Joubert] |
Full Idea: The idea of the nest in the bird's mind, where does it come from? | |
From: Joseph Joubert (Notebooks [1800], 1800) | |
A reaction: I think this is a very striking example in support of innate ideas. Most animal behaviour can be explained as responses to stimuli, but the bird seems to hold a model in its mind while it collects its materials. |
23653 | If you can't distinguish the features of a complex object, your notion of it would be a muddle [Reid] |
Full Idea: If you perceive an object, white, round, and a foot in diameter, if you had not been able to distinguish the colour from the figure, and both from the magnitude, your senses would only give you one complex and confused notion of all these mingled together | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 1) | |
A reaction: His point is that if you reject the 'abstraction' of these qualities, you still cannot deny that distinguishing them is an essential aspect of perceiving complex things. Does this mean that animals distinguish such things? |
23663 | There are axioms of taste - such as a general consensus about a beautiful face [Reid] |
Full Idea: I think there are axioms, even in matters of taste. …I never heard of any man who thought it a beauty in a human face to want a nose, or an eye, or to have the mouth on one side. | |
From: Thomas Reid (Essays on Intellectual Powers 6: Judgement [1785], 6) | |
A reaction: It is hard to disagree, but the human face may be a special case, since it is so deeply embedded in the minds of even the youngest infants. More recent artists seem able to discover beauty in very unlikely places. |
8096 | He gives his body up to pleasure, but not his soul [Joubert] |
Full Idea: He gives his body up to pleasure, but not his soul. | |
From: Joseph Joubert (Notebooks [1800], 1799) | |
A reaction: A rather crucial distinction in the world of hedonism. There seems something sincere about someone who pursues pleasure body and soul, and something fractured about the pursuit of pleasure without real commitment. The split seems possible. |
8104 | What will you think of pleasures when you no longer enjoy them? [Joubert] |
Full Idea: What will you think of pleasures when you no longer enjoy them? | |
From: Joseph Joubert (Notebooks [1800], 1802) | |
A reaction: A lovely test question for aspiring young hedonists! It doesn't follow at all that we will despise past pleasures. The judgement may be utilitarian - that we regret the pleasures that harmed others, but love the harmless ones. Shame is social. |
8097 | Virtue is hard if we are scorned; we need support [Joubert] |
Full Idea: It would be difficult to be scorned and to live virtuously. We have need of support. | |
From: Joseph Joubert (Notebooks [1800], 1800) | |
A reaction: He seems to have hit on what I take to be one of the keys to Aristotle: that virtue is a social matter, requiring both upbringing and a healthy culture. But we can help to create that culture, as well as benefiting from it. |
8106 | In raising a child we must think of his old age [Joubert] |
Full Idea: In raising a child we must think of his old age. | |
From: Joseph Joubert (Notebooks [1800], 1809) | |
A reaction: Very nice, and Aristotle would approve. If educators think much about the future, it rarely extends before the child's first job. We should be preparing good grand-parents, as well as parents and employees. Educate for retirement! |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
8105 | We can't exactly conceive virtue without the idea of God [Joubert] |
Full Idea: If we exclude the idea of God, it is impossible to have an exact idea of virtue. | |
From: Joseph Joubert (Notebooks [1800], 1808) | |
A reaction: I suspect that an 'exact' idea is impossible even with an idea of God. This is an interesting defence of the importance of God in moral thinking, but it only requires the concept of a supreme being, and not belief. |
8102 | We cannot speak against Christianity without anger, or speak for it without love [Joubert] |
Full Idea: We cannot speak against Christianity without anger, or speak for it without love. | |
From: Joseph Joubert (Notebooks [1800], 1801) | |
A reaction: This seems to be rather true at the present time, when a wave of anti-religious books is sweeping through our culture. Presumably this remark used to be true of ancient paganism, but it died away. Christianity, though, is very personal. |
