Where there is shouting, there is no true knowledge.

It is true that impatience, the mother of stupidity, praises brevity, as if such persons had not life long enough to serve them to acquire a complete knowledge of one single subject, such as the human body; and then they want to comprehend the mind of God in which the universe is included, weighing it minutely and mincing it into infinite parts, as if they had to dissect it!

Abbreviators do harm to knowledge and to love.

All knowledge which ends in words will die as quickly as it came to life, with the exception of the written word: which is its mechanical part.

The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known.

All sciences are vain and full of errors that are not born of Experience, the mother of all Knowledge.
