Is truth always context independent ? C: Truth is not context-dependent. — Vera Mont
Supposing then the farmer utters this sentence in the middle of summer.
Today is a hot day.
The thermometer would agree reading 40Celsius.
These two truth values are not only context dependent but interdependent as a hot day is affirmed to be true by the thermometer reading.
It is context dependent because it would not be a hot day in the middle of winter when the thermometer reads -5 Celsius.
And as the truthfulness of such a statement depends on mutual agreement between two or more subjects then it’s no longer subjective (context dependent) but objective (context independent) for certain statements only which are subject to change such as current heat level.
To sum up, objectively true statements are only true if accord can be given to them by the subjects to which such a statement applies hence Today is a hot day would no longer be true objectively when the mercury falls but it could be true to an Eskimo whose conception of heat is different to a farmer.
But this does not include certain statements which hold true universally such as Apples Grow on Trees. You could negate this of course by growing your own Apple artificially in a lab without the tree at all (somehow) or statements like the The Earth is Round. Objectively true, no context needed, truth value remains absolute.
