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

The scientific books written in Arabic during the Middle Ages were, for a few centuries, the main vehicle of the living science.

Some men are abstract-minded, and they naturally think first of unity and God, of wholeness, of infinity and other such concepts, while the minds of other men are concrete and they cogitate about health and disease, profit and loss. They invent gadgets and remedies; they are less interested in knowing anything than in applying whatever knowledge... to practical problems... The first are called dreamers; the second kind are recognized as practical and useful. History has often proved the shortsightedness of the practical men and vindicated the "lazy" dreamers; it has also proved that the dreamers are often mistaken.

Superstitions... are nothing but persistent errors, foolish beliefs, and irrational fears. Superstitions are infinite in number and scope... It would not do to ignore them altogether, only if we should never forget the weakness and fragility of our minds. The consciousness that superstitions are rife in our own society is a healthy shock to our self-conceit and a warning. ...it lets us judge ancient superstitions with more indulgence and with a sense of humor. We could not overlook them without falsifying the general picture nor judge them too severely without hypocrisy.
