a commonplace book
[O]ne must always take great care with what one thinks one knows, because behind it one finds concealed an endless chain of unknowns, the last of which will probably prove insoluble.
José Saramago, Seeing (2006)
See “Just the Facts,” by Jesse Elias Spafford in The New Inquiry, on pseudoscience and epistemology:
Because of the absence of any positive or negative reason for choosing one theory over another, scientific disagreement inevitably comes down to subjective and fundamentally irrational judgments about which theories seem more plausible than others. There is simply no principled way of demonstrating that one theory is more reasonable than another—no way of proving that a theory is false or true or even more proximate to the truth than its competitor.
