Work is not primarily a thing one does to live but the thing one lives to do. It is, or it should be, the full expression of the worker's faculties, the thing in which he finds spiritual, mental and bodily satisfaction, and the medium in which he offers himself to God.

To make a deliberate falsification for personal gain is the last, worst depth to which either scholar or artist can descend in work or life.

If we do not penalize false statements made in error, we open up the way for false statements by intention. And a false statement of fact, made deliberately, is the most serious crime a scientist can commit.
