|
1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual
|
19219
|
Metaphysical reasoning is simple enough, but the concepts are very hard
|
1. Philosophy / F. Analytic Philosophy / 6. Logical Analysis
|
19231
|
Metaphysics is turning into logic, and logic is becoming mathematics
|
3. Truth / A. Truth Problems / 6. Verisimilitude
|
19247
|
The one unpardonable offence in reasoning is to block the route to further truth
|
3. Truth / E. Pragmatic Truth / 1. Pragmatic Truth

'Holding for true' is either practical commitment, or provisional theory
|
5. Theory of Logic / B. Logical Consequence / 4. Semantic Consequence |=
|
19237
|
Deduction is true when the premises facts necessarily make the conclusion fact true
|
5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic
|
19256
|
Our research always hopes that reality embodies the logic we are employing
|
5. Theory of Logic / E. Structures of Logic / 6. Relations in Logic

The logic of relatives relies on objects built of any relations (rather than on classes)
|
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / c. Conceptualism
|
19226
|
We now know that mathematics only studies hypotheses, not facts
|
7. Existence / D. Theories of Reality / 2. Realism
|
19239
|
There may be no reality; it's just our one desperate hope of knowing anything
|
|
19240
|
Realism is the belief that there is something in the being of things corresponding to our reasoning
|
10. Modality / B. Possibility / 7. Chance
|

|
10. Modality / B. Possibility / 8. Conditionals / e. Supposition conditionals

|
11. Knowledge Aims / A. Knowledge / 4. Belief / c. Aim of beliefs

We act on 'full belief' in a crisis, but 'opinion' only operates for trivial actions
|
12. Knowledge Sources / D. Empiricism / 2. Associationism

If each inference slightly reduced our certainty, science would soon be in trouble
|
14. Science / B. Scientific Theories / 1. Scientific Theory

|
I classify science by level of abstraction; principles derive from above, and data from below
|

|
'Induction' doesn't capture Greek 'epagoge', which is singulars in a mass producing the general
|
14. Science / C. Induction / 3. Limits of Induction
|
19236
|
Induction can never prove that laws have no exceptions
|
|
19251
|
The worst fallacy in induction is generalising one recondite property from a sample
|
|
19235
