If truth is the end of enquiry, what if it never ends, or ends prematurely? [Atkin on Peirce]

10. Modality / B. Possibility / 1. Possibility
Some logical possibility concerns single propositions, but there is also compatibility between propositions [Peirce]
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]

Is chance just unknown laws? But the laws operate the same, whatever chance occurs [Peirce]

Our whole conception of an object is its possible practical consequences [Peirce]

We are aware of beliefs, they appease our doubts, and they are rules of action, or habits [Peirce]
11. Knowledge Aims / A. Knowledge / 4. Belief / c. Aim of beliefs
The feeling of belief shows a habit which will determine our actions [Peirce]

A mere question does not stimulate a struggle for belief; there must be a real doubt [Peirce]

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 / 3. Fallibilism
Inquiry is not standing on bedrock facts, but standing in hope on a shifting bog [Peirce]
Reasoning is based on statistical induction, so it can't achieve certainty or precision [Peirce]
Infallibility in science is just a joke [Peirce]
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]

Association of ideas is the best philosophical idea of the prescientific age [Peirce]
12. Knowledge Sources / D. Empiricism / 3. Pragmatism
Instead of seeking Truth, we should seek belief that is beyond doubt [Peirce]

'Induction' doesn't capture Greek 'epagoge', which is singulars in a mass producing the general [Peirce]
14. Science / C. Induction / 3. Limits of Induction
How does induction get started? [Peirce]
Induction can never prove that laws have no exceptions [Peirce]
The worst fallacy in induction is generalising one recondite property from a sample [Peirce]

To understand the properties we must know the essence, as with a circle [Spinoza]
14. Science / D. Explanation / 3. Best Explanation / a. Best explanation

Indexicals are unusual words, because they stimulate the hearer to look around [Peirce]
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
