Medicine is a science which hath been (as we have said) more professed than laboured, and yet more laboured than advanced: the labour having been, in my judgment, rather in circle than in progression. For I find much iteration, but small addition. It considereth causes of diseases, with the occasions or impulsions; the diseases themselves, with the accidents; and the cures, with the preservation.
Man, being the servant and interpreter of Nature, can do and understand so much and so much only as he has observed in fact or thought of the course of nature; beyond this he neither knows anything nor can do anything.
I feel ever so strongly that an artist must be nourished by his passions and his despairs. These things alter an artist whether for the good or the better or the worse. It must alter him. The feelings of desperation and unhappiness are more useful to an artist than the feeling of contentment, because desperation and unhappiness stretch your whole sensibility.
Neither the naked hand nor the understanding left to itself can effect much. It is by instruments and helps that the work is done, which are as much wanted for the understanding as for the hand. And as the instruments of the hand either give motion or guide it, so the instruments of the mind supply either suggestions for the understanding or cautions.
Some artists leave remarkable things which, a 100 years later, don't work at all. I have left my mark; my work is hung in museums, but maybe one day the Tate Gallery or the other museums will banish me to the cellar... you never know.
There is a cunning which we in England call "the turning of the cat" in the pan; which is, when that which a man says to another, he says it as if another had said it to him.
