I accept nothing on authority. A hypothesis must be backed by reason, or else it is worthless. - Isaac Asimov

The real point of the matter is that what we call a 'wrong datum' is one which is inconsistent with all other known data. It is our only criterion for right and wrong.

Asimov: I don't know of any science fiction writer who really attempts to be a prophet. Such authors accomplish their tasks not by being correct in their predictions, necessarily, but merely by hammering home—in story after story—the notion that life is going to be different.
