i even recall some who considered skepticism to be a lifelong principle that they had to live by - there was so much falsehood in the world it was our duty to discover the truth.
it's a great learning process. there is so much to be learned when we keep asking questions, until we are sufficiently satisfied with the particular answers.
then, at some point, we get to questions that simply do not and will not have answers.
does being skeptical stop being useful at some point? should skepticism be considered a means of learning, or is it an end itself, to learn about the "ultimate truth" about whatever that needs an ultimate truth? is our search destined to be asymptotic?
