on epistemology
Surely you did not actually mean “tautology” when you described epistemology? By doing so you extend the term to cover every possible human statement about reality. When an adjective becomes universal it looses all descriptive power.
Yes, it is important to understand that no epistemology can be securely validated from a limited consciousness. The knowledge of a finite being can never be absolutely secured. But if we use the word tautology to describe that fact, we have to invent another word for those vacuous arguments which evade contradiction through obfuscatory inclusion.
An epistemology is not a tautology. The statement, “This epistemology is true,” is a tautology.
on faith
The primary difference that I see between the “faith” in material reality and “faith” in metaphysical reality is perhaps best described as inductive confidence. The first “leap of faith” is always the escape from solipsism. Nothing meaningful can be said until that leap is made. Once we accept, at least as a working hypothesis, that other human beings are conscious agents who experience a phenomenological reality, we can compare our phenomenological experience with their reports of phenomenological experience.
I have great confidence that the pencil on my desk is a material object. If I poke myself with it, I experience sharpness, penetration, pain. If I poke someone else, they will report the same group of sensations (though the particular character might change). In my life, I have never met someone who does not experience material objects in a manner directly related to my own experience. Thus my confidence level in material reality is strengthened by unchallenged and incontroverted empirical substantiation. It is not a complete induction; it can never be a complete induction. Thus, my “faith” will always be conditional. My “confidence level” will never be absolute. But uncounted thousands of phenomenological reinfocements, without a single dissent, make my confidence level quite high. As a praxis, this is indistinguishable from absolute belief (until challenged by contradictory data, of course). As an epistemological construct, it bears no relationship to absolute belief.
When people speak to me of their metaphysical beliefs, however, it is clear that they know from the outset that their phenomenological experiences are not unambiguously mirrored in the reported experiences of other humans. The confidence level for metaphysical “faith”, as best I can infer from listening to those who express it, does not decrease when contradictory or dissenting experiences are encountered. Instead, metaphysical “faith” draws its confidence either directly from the individual’s phenomenological experience or selectively from a proper subset of the external reports of experience (or both, of course). As a praxis, this is indistinguishable from absolute belief (until the direct phenomenological experience changes, of course). As an epistmological construct, the “directly supported” metaphysical faith is differentiated from absolute belief only in magnitude. The “supported by shared belief” metaphysical faith is epistemologically distinct from both absolute belief and faith in material reality.
on moral relativism
Atheist morality has been covered in great length and sometime excruciating confusion on these boards. I think some of them may have been cleared away in the “Great thread Purge of 2001”, but the search engine still finds this oldie but goodie.
Pjen, erislover, and I also got into some mildly entertaining fumblings about moral relativism, if you are interested.
