In a free man, choosing flight can show as much strength of mind as fighting [Spinoza]
23. Ethics / C. Virtue Theory / 3. Virtues / f. Compassion
A person unmoved by either reason or pity to help others is rightly called 'inhuman' [Spinoza]
Pity is a bad and useless thing, as it is a pain, and rational people perform good deeds without it [Spinoza]
Pity is not a virtue, but at least it shows a desire to live uprightly [Spinoza]

24. Political Theory / A. Basis of a State / 3. Natural Values / c. Natural rights
In nature everything has an absolute right to do anything it is capable of doing [Spinoza]
Natural rights are determined by desire and power, not by reason [Spinoza]
Spinoza extended Hobbes's natural rights to cover all possible desires and actions [Spinoza, by Tuck]
24. Political Theory / B. Nature of a State / 1. Purpose of a State
Society exists to extend human awareness [Spinoza, by Watson]
The state aims to allow personal development, so its main purpose is freedom [Spinoza]
The safety of the people is the supreme law [Hume]

24. Political Theory / B. Nature of a State / 2. State Legitimacy / c. Social contract
The idea that society rests on consent or promises undermines obedience [Hume]
We no more give 'tacit assent' to the state than a passenger carried on board a ship while asleep [Hume]
The people would be amazed to learn that government arises from their consent [Hume]
24. Political Theory / B. Nature of a State / 3. Constitutions
It would be absurd if even a free constitution did not impose restraints, for the public good [Hume]
24. Political Theory / C. Ruling a State / 2. Leaders / b. Monarchy
Kings tend to fight wars for glory, rather than for peace and liberty [Spinoza]
Monarchs are always proud, and can't back down [Spinoza]
Deposing a monarch is dangerous, because the people are used to royal authority [Spinoza]
Modern monarchies are (like republics) rule by law, rather than by men [Hume]

Nobility either share in the power of the whole, or they compose the power of the whole [Hume]

Slavery is a disgraceful crime [Spinoza]
Slavery is not just obedience, but acting only in the interests of the master [Spinoza]
25. Social Practice / A. Freedoms / 2. Freedom of belief

The order of nature does not prohibit anything, and allows whatever appetite produces [Spinoza]
25. Social Practice / E. Policies / 2. Religion in Society

25. Social Practice / E. Policies / 5. Education / c. Teaching
The best use of talent is to teach other people to live rationally [Spinoza]
25. Social Practice / F. Life Issues / 4. Suicide

We can easily think of nature as one individual [Spinoza]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / b. Limited purposes
Nature has no particular goal in view, and final causes are mere human figments [Spinoza]
We can discover some laws of nature, but never its ultimate principles and causes [Hume]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / c. Purpose denied
Spinoza strongly attacked teleology, which is the lifeblood of classical logos [Roochnik on Spinoza]
For Spinoza eyes don't act for purposes, but follow mechanical necessity [Roochnik on Spinoza]
Final causes are figments of human imagination [Spinoza]
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
An infinite line can be marked in feet or inches, so one infinity is twelve times the other [Spinoza]

In nature there is just one infinite substance [Spinoza]
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / a. Early Modern matter
We have no good concept of solidity or matter, because accounts of them are all circular [Hume]
26. Natural Theory / C. Causation / 1. Causation
A priori it looks as if a cause could have absolutely any effect [Hume]
If a singular effect is studied, its cause can only be inferred from the types of events involved [Hume]
26. Natural Theory / C. Causation / 3. Final causes
A final cause is simply a human desire [Spinoza]
The idea of a final cause is very uncertain and unphilosophical [Hume]
26. Natural Theory / C. Causation / 7. Eliminating causation
Hume never even suggests that there is no such thing as causation [Hume, by Strawson,G]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
At first Hume said qualities are the causal entities, but later he said events [Hume, by Davidson]
26. Natural Theory / C. Causation / 8. Particular Causation / c. Conditions of causation
For Hume a constant conjunction is both necessary and sufficient for causation [Hume, by Crane]
26. Natural Theory / C. Causation / 9. General Causation / a. Constant conjunction
Hume says we can only know constant conjunctions, not that that's what causation IS [Hume, by Strawson,G]
Causation is just invariance, as long as it is described in general terms [Quine on Hume]
If impressions, memories and ideas only differ in vivacity, nothing says it is memory, or repetition [Whitehead on Hume]
In both of Hume's definitions, causation is extrinsic to the sequence of events [Psillos on Hume]
Hume's definition of cause as constantly joined thoughts can't cover undiscovered laws [Ayer on Hume]
A cause is either similar events following one another, or an experience always suggesting a second experience [Hume]
It is only when two species of thing are constantly conjoined that we can infer one from the other [Hume]
No causes can be known a priori, but only from experience of constant conjunctions [Hume]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Cause is where if the first object had not been, the second had not existed [Hume]
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
From a definite cause an effect necessarily follows [Spinoza]
Hume seems to presuppose necessary connections between mental events [Kripke on Hume]
That events could be uncaused is absurd; I only say intuition and demonstration don't show this [Hume]
In observing causes we can never observe any necessary connections or binding qualities [Hume]
Hume never shows how a strong habit could generate the concept of necessity [Harré/Madden on Hume]
Hume's regularity theory of causation is epistemological; he believed in some sort of natural necessity [Hume, by Strawson,G]
28. God / A. Divine Nature / 1. God
The key question for Spinoza is: is his God really a God? [Stewart,M on Spinoza]
28. God / A. Divine Nature / 2. Divine Nature
God is a substance with infinite attributes [Spinoza]
God does not act according to the freedom of the will [Spinoza]
Spinoza's God is just power and necessity, without perfection or wisdom [Leibniz on Spinoza]
Spinoza's God is not a person [Spinoza, by Jolley]
God is wholly without passions, and strictly speaking does not love anyone [Spinoza, by Cottingham]
God is the sum and principle of all eternal laws [Spinoza, by Armstrong,K]
God is not loveable for producing without choice and by necessity; God is loveable for his goodness [Leibniz on Spinoza]
God has no purpose, because God lacks nothing [Spinoza]
God feels no emotions, of joy or sorrow [Spinoza]
28. God / A. Divine Nature / 3. Divine Perfections
We can't assume God's perfections are like our ideas or like human attributes [Hume]
God is a being with infinite attributes, each of them infinite or perfect [Spinoza]
God no more has human perfections than we have animal perfections [Spinoza]
28. God / A. Divine Nature / 6. Divine Morality / c. God is the good
To say that God promotes what is good is false, as it sets up a goal beyond God [Spinoza]
28. God / B. Proving God / 1. Proof of God
The objects of theological reasoning are too big for our minds [Hume]
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
Some things makes me conceive of it as a thing whose essence requires its existence [Spinoza]
Spinoza says a substance of infinite attributes cannot fail to exist [Spinoza, by Lord]
Denial of God is denial that his essence involves existence, which is absurd [Spinoza]
God is being as such, and you cannot conceive of the non-existence of being [Spinoza, by Lord]
God must necessarily exist, because no reason can be given for his non-existence [Spinoza]
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
If a thing can be conceived as non-existing, its essence does not involve existence [Spinoza]
It can never be a logical contradiction to assert the non-existence of something thought to exist [Hume]
No being's non-existence can imply a contradiction, so its existence cannot be proved a priori [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / a. Cosmological Proof
A chain of events requires a cause for the whole as well as the parts, yet the chain is just a sum of parts [Hume]
If something must be necessary so that something exists rather than nothing, why can't the universe be necessary? [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof
The thing which contains order must be God, so see God where you see order [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / c. Teleological Proof critique
From our limited view, we cannot tell if the universe is faulty [Hume]
Design cannot prove a unified Deity. Many men make a city, so why not many gods for a world? [Hume]
You can't infer the cause to be any greater than its effect [Hume]
If the divine cause is proportional to its effects, the effects are finite, so the Deity cannot be infinite [Hume]
From a ship you would judge its creator a genius, not a mere humble workman [Hume]
This excellent world may be the result of a huge sequence of trial-and-error [Hume]
Humans renew their species sexually. If there are many gods, would they not do the same? [Hume]
Creation is more like vegetation than human art, so it won't come from reason [Hume]
This Creator god might be an infant or incompetent or senile [Hume]
Motion often begins in matter, with no sign of a controlling agent [Hume]
The universe could settle into superficial order, without a designer [Hume]
Ideas arise from objects, not vice versa; ideas only influence matter if they are linked [Hume]
A surprise feature of all products of 9 looks like design, but is actually a necessity [Hume]
Why would we infer an infinite creator from a finite creation? [Hume]
How can we pronounce on a whole after a brief look at a very small part? [Hume]
Analogy suggests that God has a very great human mind [Hume]
The universe may be the result of trial-and-error [Hume]
Order may come from an irrational source as well as a rational one [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / e. Miracles
A miracle violates laws which have been established by continuous unchanging experience, so should be ignored [Hume]
All experience must be against a supposed miracle, or it wouldn't be called 'a miracle' [Hume]
To establish a miracle the falseness of the evidence must be a greater miracle than the claimed miraculous event [Hume]
Trying to prove God's existence through miracles is proving the obscure by the more obscure [Spinoza]
Priests reject as heretics anyone who tries to understand miracles in a natural way [Spinoza]
It can't be more rational to believe in natural laws than miracles if the laws are not rational [Ishaq on Hume]
28. God / C. Attitudes to God / 2. Pantheism
That God is the substance of all things is an ill-reputed doctrine [Leibniz on Spinoza]
God is the efficient cause of essences, as well as of existences [Spinoza]
The human mind is part of the infinite intellect of God [Spinoza]
Everything is in God, and nothing exists or is thinkable without God [Spinoza]
28. God / C. Attitudes to God / 4. God Reflects Humanity
The idea of an infinite, intelligent, wise and good God arises from augmenting the best qualities of our own minds [Hume]
A talking triangle would say God is triangular [Spinoza]
28. God / C. Attitudes to God / 5. Atheism
In Spinoza, one could substitute 'nature' or 'substance' for the word 'God' throughout [Spinoza, by Stewart,M]
29. Religion / B. Monotheistic Religion / 2. Judaism
Hebrews were very hostile to other states, who had not given up their rights to God [Spinoza]
29. Religion / B. Monotheistic Religion / 5. Bible
The Bible has nothing in common with reasoning and philosophy [Spinoza]
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
Spinoza's theory of mind implies that there is no immortality [Spinoza, by Stewart,M]
After death, something eternal remains of the mind [Spinoza]
If all of my perceptions were removed by death, nothing more is needed for total annihilation [Hume]
