31 ideas

2. Reason / A. Nature of Reason / 9. Limits of Reason
A rational donkey would starve to death between two totally identical piles of hay [Buridan, by PG]
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / l. Limits
The modern idea of 'limit' allows infinite quantities to have a finite sum [Bardon]
7. Existence / A. Nature of Existence / 3. Being / e. Being and nothing
An equally good question would be why there was nothing instead of something [Bardon]
9. Objects / C. Structure of Objects / 4. Quantity of an Object
Without magnitude a thing would retain its parts, but they would have no location [Buridan]
9. Objects / E. Objects over Time / 8. Continuity of Rivers
A thing is (less properly) the same over time if each part is succeeded by another [Buridan]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / b. Primary/secondary
Why can't we deduce secondary qualities from primary ones, if they cause them? [Buridan]
14. Science / A. Basis of Science / 2. Demonstration
Induction is not demonstration, because not all of the instances can be observed [Buridan]
14. Science / C. Induction / 2. Aims of Induction
Science is based on induction, for general truths about fire, rhubarb and magnets [Buridan]
14. Science / D. Explanation / 2. Types of Explanation / j. Explanations by reduction
Six reduction levels: groups, lives, cells, molecules, atoms, particles [Putnam/Oppenheim, by Watson]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Why does an effect require a prior event if the prior event isn't a cause? [Bardon]
27. Natural Reality / A. Classical Physics / 2. Thermodynamics / d. Entropy
Becoming disordered is much easier for a system than becoming ordered [Bardon]
27. Natural Reality / C. Space / 6. Space-Time
The universe expands, so space-time is enlarging [Bardon]
27. Natural Reality / D. Time / 1. Nature of Time / c. Idealist time
We should treat time as adverbial, so we don't experience time, we experience things temporally [Bardon, by Bardon]
27. Natural Reality / D. Time / 1. Nature of Time / i. Denying time
How can we question the passage of time, if the question takes time to ask? [Bardon]
27. Natural Reality / D. Time / 2. Passage of Time / b. Rate of time
What is time's passage relative to, and how fast does it pass? [Bardon]
27. Natural Reality / D. Time / 2. Passage of Time / e. Tensed (A) series
The A-series says a past event is becoming more past, but how can it do that? [Bardon]
27. Natural Reality / D. Time / 2. Passage of Time / f. Tenseless (B) series
The B-series needs a revised view of causes, laws and explanations [Bardon]
The B-series is realist about time, but idealist about its passage [Bardon]
The B-series adds directionality when it accepts 'earlier' and 'later' [Bardon]
27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow
To define time's arrow by causation, we need a timeless definition of causation [Bardon]
We judge memories to be of the past because the events cause the memories [Bardon]
The psychological arrow of time is the direction from our memories to our anticipations [Bardon]
The direction of entropy is probabilistic, not necessary, so cannot be identical to time's arrow [Bardon]
It is arbitrary to reverse time in a more orderly universe, but not in a sub-system of it [Bardon]
27. Natural Reality / D. Time / 2. Passage of Time / h. Change in time
It seems hard to understand change without understanding time first [Bardon]
We experience static states (while walking round a house) and observe change (ship leaving dock) [Bardon]
27. Natural Reality / D. Time / 2. Passage of Time / i. Time and motion
The motion of a thing should be a fact in the present moment [Bardon]
Experiences of motion may be overlapping, thus stretching out the experience [Bardon]
27. Natural Reality / D. Time / 2. Passage of Time / j. Time travel
At least eternal time gives time travellers a possible destination [Bardon]
Time travel is not a paradox if we include it in the eternal continuum of events [Bardon]
27. Natural Reality / D. Time / 3. Parts of Time / d. Measuring time
We use calendars for the order of events, and clocks for their passing [Bardon]
