Darwin Says ” all observation must be for or against some view if it is to be of any service.” “There was much talk that geologists ought only observe and not theorize; and I will remember someone saying that at this rate, a man might as well go into a gravel-pit and count the pebbles and describe the colors. 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 1861
