4. Formal Logic / F. Set Theory ST / 3. Types of Set / b. Empty (Null) Set
14239 The empty set is usually derived from Separation, but it also seems to need Infinity [Oliver/Smiley]
14240 The empty set is something, not nothing! [Oliver/Smiley]
14241 We don't need the empty set to express non-existence, as there are other ways to do that [Oliver/Smiley]
14242 Maybe we can treat the empty set symbol as just meaning an empty term [Oliver/Smiley]
4. Formal Logic / F. Set Theory ST / 3. Types of Set / c. Unit (Singleton) Sets
14243 The unit set may be needed to express intersections that leave a single member [Oliver/Smiley]
5. Theory of Logic / G. Quantification / 6. Plural Quantification
14234 If you only refer to objects one at a time, you need sets in order to refer to a plurality [Oliver/Smiley]
14237 We can use plural language to refer to the set theory domain, to avoid calling it a 'set' [Oliver/Smiley]
5. Theory of Logic / I. Semantics of Logic / 3. Logical Truth
14245 Logical truths are true no matter what exists - but predicate calculus insists that something exists [Oliver/Smiley]
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / g. Applying mathematics
14246 If mathematics purely concerned mathematical objects, there would be no applied mathematics [Oliver/Smiley]
6. Mathematics / B. Foundations for Mathematics / 6. Mathematics as Set Theory / a. Mathematics is set theory
14247 Sets might either represent the numbers, or be the numbers, or replace the numbers [Oliver/Smiley]
8. Modes of Existence / B. Properties / 8. Properties as Modes
16730 If matter is entirely atoms, anything else we notice in it can only be modes [Gassendi]
14. Science / D. Explanation / 2. Types of Explanation / j. Explanations by reduction
16619 We observe qualities, and use 'induction' to refer to the substances lying under them [Gassendi]
15. Nature of Minds / C. Capacities of Minds / 9. Perceiving Causation
17527 Causation seems to be an innate concept (or acquired very early) [Bird]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / g. Atomism
16593 Atoms are not points, but hard indivisible things, which no force in nature can divide [Gassendi]
16729 How do mere atoms produce qualities like colour, flavour and odour? [Gassendi]
26. Natural Theory / C. Causation / 2. Types of cause
17528 The dispositional account explains causation, as stimulation and manifestation of dispositions [Bird]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
17526 The counterfactual approach makes no distinction between cause and pre-condition [Bird]
