“I am not really the helpless type, but I have never been very fond of the sort of aggressive scholarship that is now encountered everywhere, trying to sell to humanity brand-new laws of nature as if they were used cars. A feeling of tentativeness; an appreciation of the provisional and fragmentary character of human insight into nature; a consideration of how much arrogance and rashness must attend even the deepest understanding before generalizing statements can be made about life: all this will be part of the inheritance with which the many years have burdened the scientist as he grows older. If he is any good, he will become more modest.” (Erwin Chargaff, Heraclitean Fire)
