Blaise Pascal (1651)

It is thus that geometry, arithmetic, music, physics, medicine, architecture, and all the sciences that are subject to experiment and reasoning, should be augmented in order to become perfect. The ancients found them merely outlined by those who preceded them; and we shall leave them to those who will come after us in a more finished state than we received them.

As their perfection depends on time and pains, it is evident that although our pains and time may have acquired less than their labors separate from ours, both joined together must nevertheless have more effect than each one alone.
