|Time: A. Time is a dimension in which events are arranged. At first, no direction (before / after) is defined with this. A time direction can be obtained in the context of the Second Principle of Thermodynamics. However, a global framework must be assumed, within which there is an increase of entropy. The assumption of increasing entropy does not apply to the comparison of local events. B. In the case of the subjective time, the question of direction is less problematic. The perceived time direction is expressed by the learned use of the terms "before" and "after". See also time arrow, time travel, time reversal, symmetry, duration, space time, relativity theory, four-dimensionalism, world lines._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Predicate/Existence/Woods: E.g. "There were dodos": Dodo: one-digit predicate that is only true of an object if it belongs to the extension of the predicate at that time - i. e. relative to the time of the utterance - with some predicates one associates the non-applicability with the passing of the object, with others not - always true during existence: "Human" - sometimes true, but only if object exists:"sleeps" -sometimes true, but even if object does not exist: famous.
Fulfilment/Time/Existence/Woods: Errors: to think, fulfillment (as a predicate in the meta-language) did not need to be relativized on time. Fulfillment here is not a classic two-digit predicate, true of pairs of expressions and sequences - but if truth is relative to time, it must be possible for the same sentence to be fulfilled even in the mouth of the same speaker by all sequences at some time and not at any other time.
Existence/Time/Woods: another approach: predicates should carry temporal relativization, not the quantifiers. When are indices and demonstratives necessary. Indexical singular terms should be treated with the attribution function*, so that objects are linked with expressions by triplets from a sequence, a person and a time - "There were dodos": Dodo is here a two-digit predicate, true of object at a time when it is a dodo - here too we bear the implication of past existence by the meaning of "dodo".
Problem: future existence cannot be expressed if "F" is the only predicate - past and future are indistinguishable - solution: combining both approaches:
a) Indexical sentence operators.
b) To introduce time into predicates: so that one can say that it is now true that something is F in the future and that it will be true that something is F then._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
