Simple Distinctions Come All Too Easily

Multiple Choice

Simple distinctions come all too easily. Frequently we open the way for later puzzlement by restricting the options we take to be available.

On one side there is science, proof, and certainty; on the other, religion, conjecture, and faith. (Philip Kitcher, Abusing Science: The Case Against Creationism)
