3. Truth / B. Truthmakers / 5. What Makes Truths / d. Being makes truths
The weaker version of Truthmaker: 'truth supervenes on being' [Crisp,TM]
3. Truth / B. Truthmakers / 9. Making Past Truths
The Truthmaker thesis spells trouble for presentists [Crisp,TM]
3. Truth / B. Truthmakers / 12. Rejecting Truthmakers
Truthmaker has problems with generalisation, non-existence claims, and property instantiations [Crisp,TM]
5. Theory of Logic / A. Overview of Logic / 7. Second-Order Logic
Second-order logic needs the sets, and its consequence has epistemological problems [Rossberg]
Henkin semantics has a second domain of predicates and relations (in upper case) [Rossberg]
There are at least seven possible systems of semantics for second-order logic [Rossberg]
5. Theory of Logic / B. Logical Consequence / 2. Types of Consequence
Logical consequence is intuitively semantic, and captured by model theory [Rossberg]
5. Theory of Logic / B. Logical Consequence / 3. Deductive Consequence |-
Γ |- S says S can be deduced from Γ; Γ |= S says a good model for Γ makes S true [Rossberg]
5. Theory of Logic / E. Structures of Logic / 1. Logical Form
In proof-theory, logical form is shown by the logical constants [Rossberg]
5. Theory of Logic / J. Model Theory in Logic / 1. Logical Models
A model is a domain, and an interpretation assigning objects, predicates, relations etc. [Rossberg]
5. Theory of Logic / J. Model Theory in Logic / 2. Isomorphisms
If models of a mathematical theory are all isomorphic, it is 'categorical', with essentially one model [Rossberg]
5. Theory of Logic / K. Features of Logics / 4. Completeness
Completeness can always be achieved by cunning model-design [Rossberg]
5. Theory of Logic / K. Features of Logics / 5. Incompleteness
A deductive system is only incomplete with respect to a formal semantics [Rossberg]
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
Worm Perdurantism has a fusion of all the parts; Stage Perdurantism has one part at a time [Crisp,TM]
23. Ethics / C. Virtue Theory / 3. Virtues / a. Virtues
Unlike us, the early Greeks thought envy was a good thing, and hope a bad thing [Hesiod, by Nietzsche]
27. Natural Reality / D. Time / 1. Nature of Time / f. Eternalism
'Eternalism' is the thesis that reality includes past, present and future entities [Crisp,TM]
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
Presentists can talk of 'times', with no more commitment than modalists have to possible worlds [Crisp,TM]
27. Natural Reality / D. Time / 2. Passage of Time / d. Time series
The only three theories are Presentism, Dynamic (A-series) Eternalism and Static (B-series) Eternalism [Crisp,TM]
