“About thirty years ago there was much talk that geology ought only to observe and theorise: and I well remember someone saying that at this rate man might well go into a gravel pit and count the pebbles and describe the colours. How odd it is that anyone should not see that all observation must be for or against some view if it is to be of any service.”

Charles Darwin to Henry Fawcett, 1861.
