) For
example, how would one state a truth condition for the sentence "I am sick
now"? "`I am sick now' is true if and only if I am sick now" would never do,
since its truth-value depends on who utters it and when and is not in general
determined by my (your humble narrator's) state of health. Deictic sentences
do not even have truth-values, except on actual or hypothetical occasions of
their use (a point that would gratify Strawson).
Davidson's own response is to relativize truth to a speaker and a time.
The relevant T-sentence would be formulated as, "`I am sick now' is true as
potentially spoken by p at t if and only if p is sick at t." But this is unsatisfac-
tory in each of several ways,5 not least in that speaker and time of utterance
are not the only contextual factors that affect truth-value. (Recall "This is a
fine red one.") We shall return to this issue in chapter 11.6
