7113 Phenomenology assumes that all consciousness is of something [Sartre]
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]

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]

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]
11. Knowledge Aims / B. Certain Knowledge / 5. Cogito Critique
7114 The consciousness that says 'I think' is not the consciousness that thinks [Sartre]
7112 The Cogito depends on a second-order experience, of being conscious of consciousness [Sartre]
7119 Is the Cogito reporting an immediate experience of doubting, or the whole enterprise of doubting? [Sartre]
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / b. Scepticism of other minds
7122 We can never, even in principle, grasp other minds, because the Ego is self-conceiving [Sartre]
7125 A consciousness can conceive of no other consciousness than itself [Sartre]

7108 The eternal truth of 2+2=4 is what gives unity to the mind which regularly thinks it [Sartre]

7111 Consciousness exists as consciousness of itself [Sartre]
15. Nature of Minds / B. Features of Minds / 2. Unconscious Mind

7106 The Ego is not formally or materially part of consciousness, but is outside in the world [Sartre]
16. Persons / C. Self-Awareness / 2. Knowing the Self

7123 Knowing yourself requires an exterior viewpoint, which is necessarily false [Sartre]
22225 My ego is more intimate to me, but not more certain than other egos [Sartre]
16. Persons / C. Self-Awareness / 3. Limits of Introspection
7116 When we are unreflective (as when chasing a tram) there is no 'I' [Sartre]
7124 The Ego never appears except when we are not looking for it [Sartre]
16. Persons / D. Continuity of the Self / 2. Mental Continuity / a. Memory is Self
7120 It is theoretically possible that the Ego consists entirely of false memories [Sartre]
16. Persons / D. Continuity of the Self / 4. Split Consciousness
7110 If the 'I' is transcendental, it unnecessarily splits consciousness in two [Sartre]
16. Persons / E. Rejecting the Self / 4. Denial of the Self
