The greater the scientist, the more he is impressed with his ignorance of reality, and the more he realizes that his laws and labels, descriptions and definitions, are the products of his own thought. They help him to use the world for purposes of his own devising rather than understand and explain it.
He who knows much about others may be learned, but he who understands himself is more intelligent. He who controls others may be powerful, but he who has mastered himself is mightier still.
For there is a great difference in delivery of the mathematics , which are the most abstracted of knowledges, and policy , which is the most immersed. And howsoever contention hath been moved , touching a uniformity of method in multiformity of matter, yet we see how that opinion, besides the weakness of it, hath been of ill desert towards learning, as that which taketh the way to reduce learning to certain empty and barren generalities; being but the very husks and shells of sciences, all the kernel being forced out and expulsed with the torture and press of the method.
It is by discourse that men associate, and words are imposed according to the apprehension of the vulgar. And therefore the ill and unfit choice of words wonderfully obsesses the understanding. Nor do the definitions or explanations wherewith in some things learned men are wont to guard and defend themselves, by any means set the matter right. But words plainly force and overrule the understanding, and throw all into confusion, and lead men away into innumerable and inane controversies and fancies.
The bookful blockhead ignorantly read, With loads of learned lumber in his head, With his own tongue still edifies his ears, And always list'ning to himself appears. All books he reads, and all he reads assails.
I praise God for you, sir: your reasons at dinner have been sharp and sententious; pleasant without scurrility, witty without affectation, audacious without impudency, learned without opinion, and strange with-out heresy.
Enflamed with the study of learning and the admiration of virtue; stirred up with high hopes of living to be brave men and worthy patriots, dear to God, and famous to all ages.
Learning hath his infancy, when it is but beginning and almost childish; then his youth, when it is luxuriant and juvenile; then his strength of years, when it is solid and reduced; and lastly his old age, when it waxeth dry and exhaust.
