Single Idea 8186

[filed under theme 27. Natural Reality / D. Time / 1. Nature of Time / d. Time as measure ]

Full Idea

Time is the measure of change, and it makes no sense to speak of how things were before there was anything that changed.

Gist of Idea

Time is the measure of change, so we can't speak of time before all change

A Reaction

Something creating its own measure sounds like me marking my own exam papers. If an object appears, then inverts five seconds later, how can the inversion create the five seconds? How does that differ from inverting ten seconds later?

The 21 ideas from 'Thought and Reality'

8163 Since 'no bird here' and 'no squirrel here' seem the same, we must talk of 'atomic' facts [Dummett]
8161 We know we can state facts, with true statements [Dummett]
8165 To 'abstract from' is a logical process, as opposed to the old mental view [Dummett]
8166 Truth is part of semantics, since valid inference preserves truth [Dummett]
8167 If Presentism is correct, we cannot even say that the present changes [Dummett]
8168 To know the truth-conditions of a sentence, you must already know the meaning [Dummett]
8170 Sentences are the primary semantic units, because they can say something [Dummett]
8169 We can't distinguish a proposition from its content [Dummett]
8175 A theory of thought will include propositional attitudes as well as propositions [Dummett]
8174 The theories of meaning and understanding are the only routes to an account of thought [Dummett]
8173 Language can violate bivalence because of non-referring terms or ill-defined predicates [Dummett]
8176 We could only guess the meanings of 'true' and 'false' when sentences were used [Dummett]
8179 The law of excluded middle is the logical reflection of the principle of bivalence [Dummett]
8180 'That is red or orange' might be considered true, even though 'that is red' and 'that is orange' were not [Dummett]
8178 Empirical and a priori knowledge are not distinct, but are extremes of a sliding scale [Dummett]
8181 A justificationist theory of meaning leads to the rejection of classical logic [Dummett]
8182 Verificationism could be realist, if we imagined the verification by a superhuman power [Dummett]
8183 If truths about the past depend on memories and current evidence, the past will change [Dummett]
8184 Philosophers should not presume reality, but only invoke it when language requires it [Dummett]
8185 We can't make sense of a world not apprehended by a mind [Dummett]
8186 Time is the measure of change, so we can't speak of time before all change [Dummett]
