I care not what subject is taught, if only it be taught well.

If a man cannot do brain work without stimulants of any kind, he had better turn to hand work it is an indication on Nature's part that she did not mean him to be a head worker.

If a man cannot see a church, it is preposterous to take his opinion about its altar-piece or painted window.

The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind.
