Substance Quotes - page 13
It is in this way that all my books have been composed. They were always written at least twice over; a first draft of the entire work was completed to the very end of the subject, then the whole begun again de novo; but incorporating, in the second writing, all sentences and parts of sentences of the old draft, which appeared as suitable to my purpose as anything which I could write in lieu of them. I have found great advantages in this system of double redaction. It combines, better than any other mode of composition, the freshness and vigour of the first conception, with the superior precision and completeness resulting from prolonged thought. In my own case, moreover, I have found that the patience necessary for a careful elaboration of the details of composition and expression, costs much less effort after the entire subject has been once gone through, and the substance of all that I find to say has in some manner, however imperfect, been got upon paper.
John Stuart Mill
[O]f articles of food, those which are unsuitable and hurtful to man when administered, every one is either bitter... or saltish or acid, or something else intense and strong, and therefore we are disordered by them... But all those things of which a man eats and drinks are devoid of any such intense and well-marked quality... which man is accustomed to use for food, with the exception of condiments and confectionaries, which are made to gratify the palate and for luxury. And from those things, when received into the body abundantly, there is no disorder nor dissolution of the powers belonging to the body; but strength, growth, and nourishment... for no other reason than because they are well mixed, have no thing in them of an immoderate character, nor anything strong, but the whole forms... [of] simple and not strong substance.
Hippocrates
Opponents of Fracastoro met his arguments by feigning imaginary causes, which differed from each other rather in name than in substance. Andrea Mattioli, for instance, an eminent botanist, the illustrator of Dioscorides, embraced the notion of Agricola, a German miner, that a certain 'materia pinguis' or 'fatty matter,' set into fermentation by heat, gave birth to fossil organic shapes. Yet Mattioli had come to the conclusion, from his own observations, that porous bodies, such as bones and shells, might be converted into stone, as being permeable to what he termed the 'lapidifying juice.
