Substance Quotes

“How frail and ephemeral is the material substance of letters, which makes their very survival so hazardous. Print has a permanence of its own, though it may not be much worth preserving, but a letter! Conveyed by uncertain transportation, over which the sender has no control; committed to a single individual who may be careless or inappreciative; left to the mercy of future generations, of families maybe anxious to suppress the past, of the accidents of removals and house-cleanings, or of mere ignorance. How often it has been by the veriest chance that they have survived at all.”

“I was a student, and as such you generally rely on prior models of how to make art, but these were not satisfying. Then I discovered in photos what had been missing in paintings; namely that they make a terrific variety of statements and have great substance. That is what I wanted to convey to paintings and apply to it.”

“Whether you know it or not, one of the most important relationships in your life is with your Soul. Will you be kind and loving to your Soul, or will you be harsh and difficult? Many of us unknowingly damage our Souls with our negative attitudes and actions or by simple neglect. By making the relationship with your Soul an important part of your life, however, by honoring it in your daily routine, you give your life greater meaning and substance. Use your experiences-all of them-as opportunities to nourish your Soul!”

“I propose to provide proof... that just as always an alcoholic ferment, the yeast of beer, is found where sugar is converted into alcohol and carbonic acid, so always a special ferment, a lactic yeast, is found where sugar is transformed into lactic acid. And, furthermore, when any plastic nitrogenated substance is able to transform sugar into that acid, the reason is that it is a suitable nutrient for the growth of the [lactic] ferment.”

“Compare ... the various quantities of the same element contained in the molecule of the free substance and in those of all its different compounds and you will not be able to escape the following law: The different quantities of the same element contained in different molecules are all whole multiples of one and the same quantity, which always being entire, has the right to be called an atom.”

“The most startling result of Faraday's Law is perhaps this. If we accept the hypothesis that the elementary substances are composed of atoms, we cannot avoid concluding that electricity also, positive as well as negative, is divided into definite elementary portions, which behave like atoms of electricity.”

“[1.] And first I suppose that there is diffused through all places an aethereal substance capable of contraction & dilatation, strongly elastick, & in a word, much like air in all respects, but far more subtile. 2. I suppose this aether pervades all gross bodies, but yet so as to stand rarer in their pores then in free spaces, & so much ye rarer as their pores are less ... 3. I suppose ye rarer aether within bodies & ye denser without them, not to be terminated in a mathematical superficies, but to grow gradually into one another.”

“I am thinking, therefore I exist. (...) I was a substance whose whole essence or nature is solely to think, and which does not require any place, or depend on any material thing, in order to exist. Accordingly this 'I' - that is, the soul by which I am what I am - is entirely distinct from the body, and indeed is easier to know than the body, and would not fail to be whatever it is, even if the body did not exist.”

“The human body contains blood, phlegm, yellow bile and black bile. These are the things that make up its constitution and cause its pain and health. Health is primarily that state in which these constituent substances are in the correct proportion to each other, both in strength and quantity, and are well mixed.”

“The most callous, stupid things were done just because regulations required them...It was not until 1983, for example, that U.S. federal agencies stated that substances known to be caustic irritants such as lye, ammonia, and oven cleaners, did not need to be tested on the eyes of conscious rabbits.”
