Proposition 2: What about the "truths" of science? Are they true'? Much has been written about the inherent provisionality of scientific theories. Karl Popper has told us that we never prove a theory right; we merely fail to prove it wrong .32 Thomas Kuhn has told us that scientific theories undergo wholesale revision with each generation and therefore do not converge on the truth .33 There's no telling which of our current theories will be proved wrong tomorrow, so how much confidence can we have in them? Many unwary consumers of these ideas have concluded that science is just another area of human discourse and, as such, is no more anchored to the facts of this world than literature or religion are. All truths are up for grabs.
