Thomas Henry Huxley Quote
The great danger which besets all men of large speculative faculty, is the temptation to deal with the accepted statements of facts in natural science, as if they were not only correct, but exhaustive; as if they might be dealt with deductively, in the same was a proposition in Euclid may be dealt with.
