Fuzzy logics are systems of logic with infinitely many truth values. Such logics have been claimed to have an extremely wide range of applications in linguistics, computer technology, psychology, etc. In this note, we canvass the known results concerning infinitely many valued logics; make some suggestions for alterations of the known systems in order to accommodate what modern devotees of fuzzy logic claim to desire; and we prove some theorems to the effect that there can be no fuzzy logic which (...) will do what its advocates want. Finally, we suggest ways to accommodate these desires in finitely many valued logics. (shrink)

This essay shows that truth cannot be divorced from human experience and an individual’s world view, his or her weltanschauung. There exist different weltanschauungen that favour alternative truths. Thus, loosely speaking, truth is determined by context. It may be socially acceptable to prefer one among the alternative truths as truly true, but this goal necessarily involves taking an ideological perspective on what is perceived and accepted as the sole truth. In other words, it is prejudiced. The truth value assigned to (...) the proposition God exists starkly illustrates this claim, but in the course of this essay I demonstrate that alternative truths are widespread and that conflicting truths can co-exist within a community even when they create dissension. A hegemonic group will assert a preference for one truth over its alternatives, but that does not eliminate the existence of alternative truths. Alternative weltanschauungen need to be managed somehow, and the recognition that alternative truths exist is one step in their management. (shrink)
