“Mathematical Knowledge adds a manly Vigour to the Mind, frees it from Prejudice, Credulity, and Superstition.”

“There are very few things which we know, which are not capable of being reduc'd to a Mathematical Reasoning; and when they cannot it's a sign our knowledge of them is very small and confus'd; and when a Mathematical Reasoning can be had it's as great a folly to make use of any other, as to grope for a thing in the dark, when you have a Candle standing by you.”

“Only add Deeds to thy knowledge answerable; add faith; Add virtue, patience, temperance; add love, By name to come called charity, the soul Of all the rest: then wilt thou not be loath To leave this Paradise; but shalt possess A paradise within thee, happier far.”

“The Word frees us from smallness of mind (1 Kings 4:29) and from threatening confinements (Psalm 18:19).”

“Our species is the only creative species, and it has only one creative instrument, the individual mind and spirit of man. Nothing was ever created by two men. There are no good collaborations, whether in music, in art, in poetry, in mathematics, in philosophy.

“...there is nothing so dangerous in its consequences as injustice to individuals- whether it arise from prejudice of color or from any other source; that a wrong done to one man is a wrong to society and to the world.”

“Let the human mind loose. It must be loose. It will be loose. Superstition and dogmatism cannot confine it.{Letter to his son and 6th US president, John Quincy Adams, November 13 1816}”
