I find the American Pragmatists’ definition of truth to be the most helpful (esp., Charles Pierce, William James, and John Dewey). They were able to combine the idea that there are objective facts independent of human perception (i.e., that truth isn’t located in perception) with the idea that human perceptions of those facts changes over time (i.e., that human knowledge arises from changing experiences in their environments). They argued that, in terms of human knowledge, truth is a process and is functional. This isn’t a kind of postmodern relativism (although they were relativisitic in the narrow sense), but rather the admission that human knowledge is always incomplete. First, truth is a process because it arises in its environment in human experience, rather than existing as a Thing-in-itself. Second, it is functional, because human being know truth based on whether it “works” in their environmental experience.
P, J & D argued that science is simply a formalization and refinement of the natural way that human brains gather knowledge from and about their environments: through experiencing them and thinking about their experiences. Science merely takes that natural, biological process and makes it rigorous. But science also only works because it has built into it the notion that new experiences may bring new knowledge tomorrow.
Dewey took this a step further to argue that whereas human history is about the Quest for Certainty (i.e., humans seek to understand perfectly their environments in order to control it (a theme which has since been picked up by cognitive science and most interestingly by evolutionary psychologists)), and that philosophy & science have been about achieving Certainty. Dewey argued that, since we now understand how human brains work (he was drawing this conclusion in the 1930s, when cognitive psychology was still relatively new), and since we know that environments constantly change (which he took from Darwinism) and that our brains thereby constantly adapt to those changes, that in formal searches for truth (i.e., scientific and philosophical), we must jetisson the Quest for Certainty and embrace the fact that knowledge is always Uncertain already.
What is Known at any given time by any given group or individual is Known precisely because it Works in the environment at hand (i.e., truth as function). But that Known will constantly change as the organism (human individual or group) moves through time and the experience changes (i.e., truth as process). But the objective truth which exists independent of human perception is also knowable, if only Uncertainly and impartially, through the processes and methods of science (small-s), which are to be open to experience, hold all ideas in solution to replace them when knew information demands it, and to actively seek to understand it without ever believing you have achieved Ultimate Truth. Truth is dead the instant you think you have it and that there is nothing more that can be said; truth only works, or rather it only works Correctly, when it is understood as a Process.
