ORIGINAL: tweakabelle If a proposition of the type "X is true" is tested, there are only 3 possible outcomes. These are: a) the proposition is proved. Therefore X is true; b) the proposition is disproved. Therefore X is untrue; and c) the proposition is neither proved nor disproved. If the proposition fails to be be proven true (option a) then all other possible outcomes are covered by options b & c. There are no other possible outcomes. Actually (and in universal practice, including everyday life, law, and science), there are at least two more: d) based on the preponderance of evidence, X is probably true. e) based on the preponderance of evidence, X is probably not true There are also: f) based on the evidence I have at present, I assume X true for now g) based on the evidence I have at present, I assume X false for now Your (d) and (e) are subsumed under (c). The three possibilities of proved, disproved, or neither exist in pure form only in logic and math. However, to conduct our affairs in a world where ambiguity, uncertainty, and partial knowledge prevail, we humans need actionable truths. For example: Most civil courts in the United States deem a proposition proved (i.e., true) using a preponderance of evidence standard. Now you're saying those guilty (and not guilty) verdicts have no truth value, as they are neither proved nor disproved. Falsifiable hypotheses and inductive reasoning are fundamental to the scientific method. In science, theories never become facts but are deemed forever provisionally true based on a preponderance of evidence (granted that some scientific theories are supported by so much evidence that they are tantamount to fact). Medical diagnoses are commonly based on partial and ambiguous observations. Operationally, we rely on probable truths, provisional truths, perceived truths, guesses, estimates, and working hypotheses and surprisingly few truths which are, with absolute certainty, proved, disproved or neither. quote:

ORIGINAL: eihwaz Paintings, jokes, music, love, joy, and poems are examples of artifacts and experiences which can be true but not susceptible to rational or scientific proof. Your last sentence is nonsense. I'd be curious to know why you think this. Care to elaborate? Are you claiming that propositions such as "I love my spouse," "The sunset was beautiful this evening," and "South Park really nails fourth grade" have no truth value, that no propositions within the realms of meaning and experience can? What about experiential propositions such as "The sky is blue." Actually, the sky is not intrinsically blue or any color. Is truth the sole preserve of rationalism, specifically deductive rationalism? Is the only true truth objective or deductive truth? (It seems to me that "truth" -- even rational truth -- is much more nuanced and complex than the three choices above, which was my point, but I'd like to understand your view.)
