When problems are analysed properly, they are either logical, or not philosophical at all [Russell]
2. Reason / F. Fallacies / 2. Infinite Regress
Vicious regresses force you to another level; non-vicious imply another level [Baron/Miller]

Logic gives the method of research in philosophy [Russell]
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
The logical connectives are not objects, but are formal, and need a context [Russell]
5. Theory of Logic / L. Paradox / 4. Paradoxes in Logic / a. Achilles paradox
The tortoise won't win, because infinite instants don't compose an infinitely long time [Russell]
5. Theory of Logic / L. Paradox / 7. Paradoxes of Time
A traveller takes a copy of a picture into the past, gives it the artist, who then creates the original! [Baron/Miller]
7. Existence / C. Structure of Existence / 1. Grounding / a. Nature of grounding
Grounding is intended as a relation that fits dependences between things [Baron/Miller]
7. Existence / C. Structure of Existence / 6. Fundamentals / d. Logical atoms
Atomic facts may be inferrable from others, but never from non-atomic facts [Russell]
7. Existence / D. Theories of Reality / 8. Facts / d. Negative facts
A positive and negative fact have the same constituents; their difference is primitive [Russell]

With asymmetrical relations (before/after) the reduction to properties is impossible [Russell]
8. Modes of Existence / B. Properties / 11. Properties as Sets
When we attribute a common quality to a group, we can forget the quality and just talk of the group [Russell]
9. Objects / E. Objects over Time / 2. Objects that Change
How does a changing object retain identity or have incompatible properties over time? [Baron/Miller]
10. Modality / C. Sources of Modality / 5. Modality from Actuality
Nothing is stronger than necessity, which rules everything [Thales, by Diog. Laertius]
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / c. Representative realism
Science condemns sense-data and accepts matter, but a logical construction must link them [Russell]
12. Knowledge Sources / B. Perception / 4. Sense Data / c. Unperceived sense-data
When sense-data change, there must be indistinguishable sense-data in the process [Russell]
12. Knowledge Sources / C. Rationalism / 1. Rationalism
Empirical truths are particular, so general truths need an a priori input of generality [Russell]

Objects are treated as real when they connect with other experiences in a normal way [Russell]
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
Global scepticism is irrefutable, but can't replace our other beliefs, and just makes us hesitate [Russell]
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / c. Knowing other minds
Other minds seem to exist, because their testimony supports realism about the world [Russell, by Grayling]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / c. Ultimate substances
Thales said water is the first principle, perhaps from observing that food is moist [Thales, by Aristotle]
26. Natural Theory / C. Causation / 1. Causation
Modern accounts of causation involve either processes or counterfactuals [Baron/Miller]
26. Natural Theory / C. Causation / 4. Naturalised causation
The main process theory of causation says it is transference of mass, energy, momentum or charge [Baron/Miller]
If causes are processes, what is causation by omission? (Distinguish legal from scientific causes?) [Baron/Miller]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
The counterfactual theory of causation handles the problem no matter what causes actually are [Baron/Miller]
Counterfactual theories struggle with pre-emption by a causal back-up system [Baron/Miller]
27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
Thales must have thought soul causes movement, since he thought magnets have soul [Thales, by Aristotle]
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / d. Entropy
There is no second 'law' of thermodynamics; it just reflects probabilities of certain microstates [Baron/Miller]
27. Natural Reality / C. Space / 6. Space-Time
In relativity space and time depend on one's motion, but spacetime gives an invariant metric [Baron/Miller]
27. Natural Reality / D. Time / 1. Nature of Time / f. Eternalism
The block universe theory says entities of all times exist, and time is the B-series [Baron/Miller]
27. Natural Reality / D. Time / 1. Nature of Time / g. Growing block
How can we know this is the present moment, if other times are real? [Baron/Miller]
If we are actually in the past then we shouldn't experience time passing [Baron/Miller]
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
Erzatz Presentism allows the existence of other times, with only the present 'actualised' [Baron/Miller]
How do presentists explain relations between things existing at different times? [Baron/Miller]

The error theory of time's passage says it is either a misdescription or a false inference [Baron/Miller]
27. Natural Reality / D. Time / 2. Passage of Time / b. Rate of time
It is meaningless to measure the rate of time using time itself, and without a rate there is no flow [Baron/Miller]

The C-series rejects A and B, and just sees times as order by betweenness, without direction [Baron/Miller]

The B-series can have a direction, as long as it does not arise from temporal flow [Baron/Miller]
27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow

The direction of time is either primitive, or reducible to something else [Baron/Miller]
The kaon does not seem to be time-reversal invariant, unlike the rest of nature [Baron/Miller]
Maybe the past is just the direction of decreasing entropy [Baron/Miller]
We could explain time's direction by causation: past is the direction of causes, future of effects [Baron/Miller]

Static time theory presents change as one property at t1, and a different property at t2 [Baron/Miller]

If a time traveller kills his youthful grandfather, he both exists and fails to exist [Baron/Miller]
Presentism means there no existing past for a time traveller to visit [Baron/Miller]
