We are so much preoccupied nowadays with the problems of the present and the future, that our debt to the past is sometimes apt to be overlooked. We are, in fact, inclined to take our present state of knowledge for granted, and when we think of the generations which have preceded our own, we are apt to do so with a sense of superiority and a pity for their mistakes, rather than with a sense of humility and of admiration for their achievement. (Weir, 1990)
