Truth, lies, reality, and humanity

Reality can't lie. A thing either is, or it is not. And whatever it is, unless it is sentient and deceptive, cannot be hidden from observation. Reality does not bend, nor does it (or can it) use symbolic manipulation to deceive.

Perceptions, however, can deceive. The nature of human perceptual frameworks and mechanisms are limited, flawed, and undefined. By their very nature, they are subjective and subject to incorrect and invalid conclusion, not to mention revision by even more subjective and invalid opinions.

Let's skip the math and the obvious but dry nomenclature of logic. Let us take the example of a person making a statement. The truth value of the statement is presently undefined (we don't know if he's lying or telling the truth).

Subjective perceptions are an insufficient filter through which to evaluate the truth of a symbolic assertion (a statement). In order to make a valid evaluation of a statement, perception must itself be filtered through a statistical filter. For example, does the individual have a statistically valid history of statements backed up by actions which can be objectively analyzed as truthful?

All assertions are falsifiable. True assertions are provable. False assertions typically appeal to incorrect or irrelevant faculties (emotions or category error framing attempts) and fail the test of objective, statistical validation.

It takes a liar to lie. Reality speaks for itself.
