The whole past and the whole world are alive in my heart, and I shall do my part to communicate their presence to my readers. - George Sarton

All men are our brothers. As far as the discovery of the truth is concerned, they are all working for the same purpose; they may be separated by the accidents of space and time, and by the exigencies of race, religion, nationality, and other groupings; from the point of view of eternity they are working together.

The whole iconography of ancient science is simply the fruit of wishful thinking.

Men of science have made abundant mistakes of every kind; their knowledge has improved only because of their gradual abandonment of ancient errors, poor approximations, and premature conclusions.
