1. Philosophy / A. Wisdom / 1. Nature of Wisdom
The wisdom of a free man is a meditation on life, not on death [Spinoza]
If we are not wholly wise, we should live by good rules and maxims [Spinoza]
1. Philosophy / D. Nature of Philosophy / 3. Philosophy Defined
Maybe what distinguishes philosophy from science is its pursuit of necessary truths [Sider]
1. Philosophy / E. Nature of Metaphysics / 2. Possibility of Metaphysics
Metaphysical enquiry can survive if its conclusions are tentative [Sider]
Your metaphysics is 'cheating' if your ontology won't support the beliefs you accept [Sider]
1. Philosophy / E. Nature of Metaphysics / 4. Metaphysics as Science
Metaphysics is not about what exists or is true or essential; it is about the structure of reality [Sider]
Extreme doubts about metaphysics also threaten to undermine the science of unobservables [Sider]
1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual
It seems unlikely that the way we speak will give insights into the universe [Sider]

1. Philosophy / F. Analytic Philosophy / 5. Linguistic Analysis
We must be careful to keep words distinct from ideas and images [Spinoza]
2. Reason / A. Nature of Reason / 3. Pure Reason
Reason only explains what is universal, so it is timeless, under a certain form of eternity [Spinoza]
Reason perceives things under a certain form of eternity [Spinoza]
2. Reason / A. Nature of Reason / 4. Aims of Reason
Without reason and human help, human life is misery [Spinoza]
In so far as men live according to reason, they will agree with one another [Spinoza]
2. Reason / B. Laws of Thought / 2. Sufficient Reason
There is necessarily for each existent thing a cause why it should exist [Spinoza]
2. Reason / D. Definition / 2. Aims of Definition
All the intrinsic properties of a thing should be deducible from its definition [Spinoza]
2. Reason / D. Definition / 13. Against Definition
Philosophical concepts are rarely defined, and are not understood by means of definitions [Sider]
It seems possible for a correct definition to be factually incorrect, as in defining 'contact' [Sider]
3. Truth / A. Truth Problems / 1. Truth
Truth is its own standard [Spinoza]
3. Truth / A. Truth Problems / 3. Value of Truth
We don't care about plain truth, but truth in joint-carving terms [Sider]
Spinoza's life shows that love of truth which he proclaims as the highest value [MacIntyre on Spinoza]
3. Truth / A. Truth Problems / 8. Subjective Truth
For Spinoza, 'adequacy' is the intrinsic mark of truth [Spinoza, by Scruton]
3. Truth / B. Truthmakers / 5. What Makes Truths / b. Objects make truths
Orthodox truthmaker theories make entities fundamental, but that is poor for explanation [Sider]

A true idea must correspond with its ideate or object [Spinoza]
4. Formal Logic / B. Propositional Logic PL / 2. Tools of Propositional Logic / b. Terminology of PL
'Theorems' are formulas provable from no premises at all [Sider]
4. Formal Logic / B. Propositional Logic PL / 3. Truth Tables
Truth tables assume truth functionality, and are just pictures of truth functions [Sider]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / c. System D
Intuitively, deontic accessibility seems not to be reflexive, but to be serial [Sider]
In D we add that 'what is necessary is possible'; then tautologies are possible, and contradictions not necessary [Sider]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / f. System B
System B introduces iterated modalities [Sider]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / h. System S5
S5 is the strongest system, since it has the most valid formulas, because it is easy to be S5-valid [Sider]
4. Formal Logic / D. Modal Logic ML / 5. Epistemic Logic
Epistemic accessibility is reflexive, and allows positive and negative introspection (KK and K¬K) [Sider]
4. Formal Logic / D. Modal Logic ML / 6. Temporal Logic
We can treat modal worlds as different times [Sider]
4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula
Converse Barcan Formula: □∀αφ→∀α□φ [Sider]
The Barcan Formula ∀x□Fx→□∀xFx may be a defect in modal logic [Sider]
System B is needed to prove the Barcan Formula [Sider]
The Barcan schema implies if X might have fathered something, there is something X might have fathered [Sider]

Which should be primitive in mereology - part, or overlap? [Sider]
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
There is a real issue over what is the 'correct' logic [Sider]
'It is raining' and 'it is not raining' can't be legislated, so we can't legislate 'p or ¬p' [Sider]
5. Theory of Logic / A. Overview of Logic / 6. Classical Logic
Classical logic is good for mathematics and science, but less good for natural language [Sider]
5. Theory of Logic / B. Logical Consequence / 1. Logical Consequence
The most popular account of logical consequence is the semantic or model-theoretic one [Sider]
Maybe logical consequence is more a matter of provability than of truth-preservation [Sider]
Maybe logical consequence is impossibility of the premises being true and the consequent false [Sider]
Maybe logical consequence is a primitive notion [Sider]
Modal accounts of logical consequence are simple necessity, or essential use of logical words [Sider]
5. Theory of Logic / B. Logical Consequence / 3. Deductive Consequence |-
A 'theorem' is an axiom, or the last line of a legitimate proof [Sider]

Define logical constants by role in proofs, or as fixed in meaning, or as topic-neutral [Sider]
5. Theory of Logic / E. Structures of Logic / 4. Variables in Logic
When a variable is 'free' of the quantifier, the result seems incapable of truth or falsity [Sider]

A 'total' function must always produce an output for a given domain [Sider]
5. Theory of Logic / F. Referring in Logic / 3. Property (λ-) Abstraction
λ can treat 'is cold and hungry' as a single predicate [Sider]
5. Theory of Logic / H. Proof Systems / 2. Axiomatic Proof
Good axioms should be indisputable logical truths [Sider]
No assumptions in axiomatic proofs, so no conditional proof or reductio [Sider]
5. Theory of Logic / H. Proof Systems / 3. Proof from Assumptions
Proof by induction 'on the length of the formula' deconstructs a formula into its accepted atoms [Sider]
Induction has a 'base case', then an 'inductive hypothesis', and then the 'inductive step' [Sider]
5. Theory of Logic / H. Proof Systems / 4. Natural Deduction
'Tonk' is supposed to follow the elimination and introduction rules, but it can't be so interpreted [Sider]
Natural deduction helpfully allows reasoning with assumptions [Sider]
5. Theory of Logic / H. Proof Systems / 6. Sequent Calculi
We can build proofs just from conclusions, rather than from plain formulae [Sider]
5. Theory of Logic / I. Semantics of Logic / 1. Semantics of Logic
Valuations in PC assign truth values to formulas relative to variable assignments [Sider]
5. Theory of Logic / I. Semantics of Logic / 3. Logical Truth
The semantical notion of a logical truth is validity, being true in all interpretations [Sider]
It is hard to say which are the logical truths in modal logic, especially for iterated modal operators [Sider]
5. Theory of Logic / J. Model Theory in Logic / 1. Logical Models
In model theory, first define truth, then validity as truth in all models, and consequence as truth-preservation [Sider]
5. Theory of Logic / K. Features of Logics / 4. Completeness
In a complete logic you can avoid axiomatic proofs, by using models to show consequences [Sider]
5. Theory of Logic / K. Features of Logics / 6. Compactness
Compactness surprisingly says that no contradictions can emerge when the set goes infinite [Sider]
6. Mathematics / A. Nature of Mathematics / 1. Mathematics
Mathematics deals with the essences and properties of forms [Spinoza]
6. Mathematics / A. Nature of Mathematics / 2. Geometry
The sum of its angles follows from a triangle's nature [Spinoza]
The idea of a triangle involves truths about it, so those are part of its essence [Spinoza]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / e. Peano arithmetic 2nd-order
A single second-order sentence validates all of arithmetic - but this can't be proved axiomatically [Sider]
7. Existence / A. Nature of Existence / 2. Types of Existence
Outside the mind, there are just things and their properties [Spinoza]
The more reality a thing has, the more attributes it has [Spinoza]
7. Existence / A. Nature of Existence / 5. Reason for Existence
There must always be a reason or cause why some triangle does or does not exist [Spinoza]

Supervenience is a modal connection [Sider]
7. Existence / C. Structure of Existence / 6. Fundamentals / b. Types of fundamental
Is fundamentality in whole propositions (and holistic), or in concepts (and atomic)? [Sider]
Tables and chairs have fundamental existence, but not fundamental natures [Sider]
7. Existence / C. Structure of Existence / 8. Stuff / a. Pure stuff
Unlike things, stuff obeys unrestricted composition and mereological essentialism [Sider]
7. Existence / D. Theories of Reality / 5. Naturalism
Laws of nature are universal, so everything must be understood through those laws [Spinoza]
7. Existence / D. Theories of Reality / 9. States of Affairs
We must distinguish 'concrete' from 'abstract' and necessary states of affairs. [Sider]
7. Existence / D. Theories of Reality / 10. Vagueness / f. Supervaluation for vagueness
A 'precisification' of a trivalent interpretation reduces it to a bivalent interpretation [Sider]
Supervaluational logic is classical, except when it adds the 'Definitely' operator [Sider]
A 'supervaluation' assigns further Ts and Fs, if they have been assigned in every precisification [Sider]
We can 'sharpen' vague terms, and then define truth as true-on-all-sharpenings [Sider]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / d. Commitment of theories
Accept the ontology of your best theory - and also that it carves nature at the joints [Sider]
8. Modes of Existence / A. Relations / 1. Nature of Relations
A relation is a feature of multiple objects taken together [Sider]
8. Modes of Existence / B. Properties / 3. Types of Properties
A property is intrinsic if an object alone in the world can instantiate it [Sider]

8. Modes of Existence / B. Properties / 6. Categorical Properties
Proper ontology should only use categorical (actual) properties, not hypothetical ones [Sider]
8. Modes of Existence / B. Properties / 8. Properties as Modes
A 'mode' is an aspect of a substance, and conceived through that substance [Spinoza]
8. Modes of Existence / B. Properties / 10. Properties as Predicates
Predicates can be 'sparse' if there is a universal, or if there is a natural property or relation [Sider]

Things persevere through a force which derives from God [Spinoza]
8. Modes of Existence / C. Powers and Dispositions / 4. Powers as Essence
The essence of a thing is its effort to persevere [Spinoza]
8. Modes of Existence / D. Universals / 6. Platonic Forms / d. Forms critiques
The 'universal' term 'man' is just imagining whatever is the same in a multitude of men [Spinoza]
9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
If sortal terms fix the kind and the persistence conditions, we need to know what kinds there are [Sider]
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
A thing is unified if its parts produce a single effect [Spinoza]
9. Objects / B. Unity of Objects / 2. Substance / b. Need for substance
Spinoza implies that thought is impossible without the notion of substance [Spinoza, by Scruton]
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
Substance is the power of self-actualisation [Spinoza, by Lord]
Substance is that of which an independent conception can be formed [Spinoza]
9. Objects / B. Unity of Objects / 3. Unity Problems / b. Cat and its tail
If Tib is all of Tibbles bar her tail, when Tibbles loses her tail, two different things become one [Sider]
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
Artists 'create' statues because they are essentially statues, and so lack identity with the lump of clay [Sider]
9. Objects / B. Unity of Objects / 3. Unity Problems / d. Coincident objects
The stage view of objects is best for dealing with coincident entities [Sider]
9. Objects / C. Structure of Objects / 5. Composition of an Object
'Composition as identity' says that an object just is the objects which compose it [Sider]
9. Objects / D. Essence of Objects / 1. Essences of Objects
The essence of a thing is what is required for it to exist or be conceived [Spinoza]
9. Objects / D. Essence of Objects / 6. Essence as Unifier
Essence gives existence and conception to things, and is inseparable from them [Spinoza]
9. Objects / D. Essence of Objects / 7. Essence and Necessity / b. Essence not necessities
Nothing is essential if it is in every part, and is common to everything [Spinoza]
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
All natures of things produce some effect [Spinoza]
9. Objects / D. Essence of Objects / 12. Essential Parts
Mereological essentialism says an object's parts are necessary for its existence [Sider]
9. Objects / D. Essence of Objects / 14. Knowledge of Essences
Experience does not teach us any essences of things [Spinoza]
9. Objects / D. Essence of Objects / 15. Against Essentialism
Essence (even if nonmodal) is not fundamental in metaphysics [Sider]
9. Objects / E. Objects over Time / 3. Three-Dimensionalism
Three-dimensionalists assert 'enduring', being wholly present at each moment, and deny 'temporal parts' [Sider]
Some might say that its inconsistency with time travel is a reason to favour three-dimensionalism [Sider]
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
Four-dimensionalists assert 'temporal parts', 'perduring', and being spread out over time [Sider]
4D says intrinsic change is difference between successive parts [Sider]
4D says each spatiotemporal object must have a temporal part at every moment at which it exists [Sider]
9. Objects / E. Objects over Time / 5. Temporal Parts
Temporal parts exist, but are not prior building blocks for objects [Sider]
Temporal parts are instantaneous [Sider]
How can an instantaneous stage believe anything, if beliefs take time? [Sider]
Four-dimensionalism says temporal parts are caused (through laws of motion) by previous temporal parts [Sider]
9. Objects / E. Objects over Time / 9. Ship of Theseus
The ship undergoes 'asymmetric' fission, where one candidate is seen as stronger [Sider]
9. Objects / E. Objects over Time / 11. End of an Object
Only an external cause can destroy something [Spinoza]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
There cannot be two substances with the same attributes [Spinoza]
The identity of indiscernibles is necessarily true, if being a member of some set counts as a property [Sider]
9. Objects / F. Identity among Objects / 8. Leibniz's Law
If you say Leibniz's Law doesn't apply to 'timebound' properties, you are no longer discussing identity [Sider]
Two substances can't be the same if they have different attributes [Spinoza]

'Strong' necessity in all possible worlds; 'weak' necessity in the worlds where the relevant objects exist [Sider]
10. Modality / A. Necessity / 5. Metaphysical Necessity
Maybe metaphysical accessibility is intransitive, if a world in which I am a frog is impossible [Sider]
10. Modality / A. Necessity / 6. Logical Necessity
Logical truths must be necessary if anything is [Sider]
10. Modality / A. Necessity / 10. Impossibility
Things are impossible if they imply contradiction, or their production lacks an external cause [Spinoza]
10. Modality / B. Possibility / 5. Contingency
Contingency is an illusion, resulting from our inadequate understanding [Spinoza, by Cottingham]
We only call things 'contingent' in relation to the imperfection of our knowledge [Spinoza]
Reason naturally regards things as necessary, and only imagination considers them contingent [Spinoza]
10. Modality / B. Possibility / 8. Conditionals / b. Types of conditional
'If B hadn't shot L someone else would have' if false; 'If B didn't shoot L, someone else did' is true [Sider]
10. Modality / C. Sources of Modality / 1. Sources of Necessity
Divine nature makes all existence and operations necessary, and nothing is contingent [Spinoza]
Humeans say that we decide what is necessary [Sider]
Modal terms in English are entirely contextual, with no modality outside the language [Sider]
10. Modality / C. Sources of Modality / 3. Necessity by Convention
If truths are necessary 'by convention', that seems to make them contingent [Sider]
Conventionalism doesn't seem to apply to examples of the necessary a posteriori [Sider]
10. Modality / C. Sources of Modality / 4. Necessity from Concepts
Humeans says mathematics and logic are necessary because that is how our concept of necessity works [Sider]
10. Modality / C. Sources of Modality / 5. Modality from Actuality
The world does not contain necessity and possibility - merely how things are [Sider]
10. Modality / C. Sources of Modality / 6. Necessity from Essence
Necessity is in reference to essence or to cause [Spinoza]
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / a. Conceivable as possible
People who are ignorant of true causes imagine anything can change into anything else [Spinoza]
Error does not result from imagining, but from lacking the evidence of impossibility [Spinoza]
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
A horse would be destroyed if it were changed into a man or an insect [Spinoza]
Transworld identity is not a problem in de dicto sentences, which needn't identify an individual [Sider]
10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts
Counterparts rest on similarity, so there are many such relations in different contexts [Sider]
10. Modality / E. Possible worlds / 3. Transworld Objects / e. Possible Objects
A thing is contingent if nothing in its essence determines whether or not it exists [Spinoza]
Barcan Formula problem: there might have been a ghost, despite nothing existing which could be a ghost [Sider]
11. Knowledge Aims / A. Knowledge / 1. Knowledge
Spinoza's three levels of knowledge are perception/imagination, then principles, then intuitions [Spinoza, by Scruton]

11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
True ideas intrinsically involve the highest degree of certainty [Spinoza]
You only know you are certain of something when you actually are certain of it [Spinoza]
A man who assents without doubt to a falsehood is not certain, but lacks a cause to make him waver [Spinoza]
11. Knowledge Aims / B. Certain Knowledge / 5. Cogito Critique
'I think' is useless, because it is contingent, and limited to the first person [Spinoza, by Scruton]

Once we have experienced two feelings together, one will always give rise to the other [Spinoza]
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / a. Pro-internalism
Anyone who knows, must know that they know, and even know that they know that they know.. [Spinoza]
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / b. Pro-coherentism
Encounters with things confuse the mind, and internal comparisons bring clarity [Spinoza]
14. Science / B. Scientific Theories / 2. Aim of Science
A theory which doesn't fit nature is unexplanatory, even if it is true [Sider]
14. Science / B. Scientific Theories / 8. Ramsey Sentences
If I used Ramsey sentences to eliminate fundamentality from my theory, that would be a real loss [Sider]
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
Problem predicates in induction don't reflect the structure of nature [Sider]
Two applications of 'grue' do not guarantee a similarity between two things [Sider]

To understand the properties we must know the essence, as with a circle [Spinoza]
14. Science / D. Explanation / 3. Best Explanation / b. Ultimate explanation
If the ultimate explanation is a list of entities, no laws, patterns or mechanisms can be cited [Sider]

Intentionality is too superficial to appear in the catalogue of ultimate physics [Sider]
15. Nature of Minds / C. Capacities of Minds / 1. Faculties
Faculties are either fictions, or the abstract universals of ideas [Spinoza]
15. Nature of Minds / C. Capacities of Minds / 8. Remembering Contiguity
If the body is affected by two things together, the imagining of one will conjure up the other [Spinoza]
15. Nature of Minds / C. Capacities of Minds / 10. Conatus/Striving
Our own force of persevering is nothing in comparison with external forces [Spinoza]
As far as possible, everything tries to persevere [Spinoza]
The conatus (striving) of mind and body together is appetite, which is the essence of man [Spinoza]

The poet who forgot his own tragedies was no longer the same man [Spinoza]
16. Persons / F. Free Will / 1. Nature of Free Will
A thing is free if it acts by necessity of its own nature, and the act is determined by itself alone [Spinoza]
16. Persons / F. Free Will / 2. Sources of Free Will
People are only free if they are guided entirely by reason [Spinoza]
16. Persons / F. Free Will / 5. Against Free Will
A thing is free if it acts only by the necessity of its own nature [Spinoza]
An act of will can only occur if it has been caused, which implies a regress of causes [Spinoza]
'Free will' is a misunderstanding arising from awareness of our actions, but ignorance of their causes [Spinoza]
Would we die if we lacked free will, and were poised between equal foods? Yes! [Spinoza]
The mind is not free to remember or forget anything [Spinoza]
16. Persons / F. Free Will / 6. Determinism / a. Determinism

18. Thought / A. Modes of Thought / 3. Emotions / a. Nature of emotions
Emotion is a modification of bodily energy, controlling our actions [Spinoza]
18. Thought / A. Modes of Thought / 3. Emotions / e. Basic emotions
The three primary emotions are pleasure, pain and desire [Spinoza]
The three primary emotions are pleasure, pain, and desire [Spinoza, by Goldie]
18. Thought / A. Modes of Thought / 3. Emotions / f. Emotion and reason
Minds are subject to passions if they have inadequate ideas [Spinoza]
An emotion is only bad if it hinders us from thinking [Spinoza]
18. Thought / A. Modes of Thought / 3. Emotions / g. Controlling emotions

An emotion comes more under our control in proportion to how well it is known to us [Spinoza]
18. Thought / A. Modes of Thought / 6. Judgement / b. Error
People make calculation mistakes by misjudging the figures, not calculating them wrongly [Spinoza]

Analyticity has lost its traditional role, which relied on truth by convention [Sider]
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
Claiming that actions depend on the will is meaningless; no one knows what the will is [Spinoza]
Spinoza argues that in reality the will and the intellect are 'one and the same' [Spinoza, by Cottingham]
20. Action / C. Motives for Action / 1. Acting on Desires
Whenever we act, then desire is our very essence [Spinoza]
20. Action / C. Motives for Action / 4. Responsibility for Actions
We love or hate people more strongly because we think they are free [Spinoza]
