Where does truth come from?
I’ve chosen to answer this question somewhat from the perspective of a secularist….or at least on their terms:
I would suggest there are a minimum of 3 ways to think about truth’s source:
• The universe has laws which effect science & cause and effect relationships
• Math has laws (Pythagorian theorem, 2 + 2 = 4, 5 x 5 = 25)
• You see things and say “I saw x” or “I thought I saw y” and to the extent that people are telling the truth–these self-expressions are the truth or very close representations of it
Truth is a mirroring or re-reprentations of reality. Its two things coming together in one sense. Its reality & representations (generally symbols or words) together in close unison or unison.
The alternative view–that its relative–is only partially true. Although in the case of science and math, generally those are pretty close to objective truths. Plus, if truth is relative it makes it entirely too hard to communicate or have common feelings or experiences. We have common feelings and experiences–which mean despite the differences in perspectives and filters–we still come to fundamental conclusions about the universe, life, and the human experience.
This is the reason our language, communication, conversations, and stories resonate and can create understanding and meaning. If this were not true stories or communication would resemble da da or some foreign language. However, 99% of the time, they don’t.
Also, that humans don’t have a total view–a view from all directions doesn’t refute the notion of ultimate truth existing. For instance, if I say the polar bear is dead when its really sleeping (aka hibernating)–that doesn’t change the truth or reality of the statement. Also, the beauty of language in some sense is its ability to be flexible–its ability to hold multiple meanings under one word.
