No less arrogant and ignorant than considering one's own definition of science to be the final word for the rest of mankind.
Your suggestion that science should be defined by non-scientists is like suggesting that brain surgery be defined by pianists.

No less arrogant and ignorant than considering one's own interpretation of the Bible to be the final word for the rest of mankind.
