Its importance is that if R[egulator] is fixed in its channel capacity, the law places an absolute limit to the amount of regulation (or control) that can be achieved by R, no matter how R is re-arranged internally, or how great the opportunity in T. Thus the ecologist, if his capacity as a channel is unchangeable, may be able at best only to achieve a fraction of what he would like to do. This fraction may be disposed in various ways -he may decide to control outbreaks rather than extensions, or virus infections rather than bacillary - but the quantity of control that he can exert is still bounded. So too the economist may have to decide to what aspect he shall devote his powers, and the psychotherapist may have to decide what symptoms shall be neglected and what controlled.

The steam-engine having furnished us with a means of converting heat into a motive power, and our thoughts being thereby led to regard a certain quantity of work as an equivalent for the amount of heat expended in its production, the idea of establishing theoretically some fixed relation between a quantity of heat and the quantity of work which it can possibly produce, from which relation conclusions regarding the nature of heat itself might be deduced, naturally presents itself. Already, indeed, have many successful efforts been made with this view; I believe, however, that they have not exhausted the subject, but that, on the contrary, it merits the continued attention of physicists... The most important investigation in connexion with this subject is that of S. Carnot.

Those who claim to care about the wellbeing of human beings and the preservation of our environment should become vegetarians for that reason alone. They would thereby increase the amount of grain available to feed people elsewhere, reduce pollution, save water and energy, and cease contributing to the clearing of forests; moreover, since a vegetarian diet is cheaper than one based on meat dishes, they would have more money available to devote to famine relief, population control, or whatever social or political cause they thought most urgent. ... when nonvegetarians say that "human problems come first” I cannot help wondering what exactly it is that they are doing for human beings that compels them to continue to support the wasteful, ruthless exploitation of farm animals.

[...] we can strip off all grammatical clues to sentence structure, all affixes and prepositions, and yet still achieve communication. Thus restricted to nouns, simple "stories" can be told in word chains: Woman, street, crowd, traffic, noise, haste, thief, bag, loss, scream, police.... Again, the reader's past experience of his language is sufficient to restore the missing elements, sufficiently accurately for the purpose. But of course, not only does the reader have experience of sentence structure, enabling him to supply the missing syntactical elements, but also he has experience of typical contexts in which the various words are used; many words bear an aura about with them. It might be more difficult to tell a tale about a policeman who robbed a woman, for instance, with so little redundancy!

A line cannot control pictorial space absolutely. A line may flow freely in and out space, but cannot independently create the phenomenon of push and pull necessary to plastic creation. Push and pull are expanding and contracting forces which are activated by carriers in visual motion. Planes are the most important carriers, lines and points less so.. .the picture plane reacts automatically in the opposite direction to the stimulus received; thus action continues as long as it receives stimulus in the creative process. Push answers with pull and pull with push. ... At the end of his life and the height of his capacity Cézanne understood color as a force of push and pull. In his pictures he created an enormous sense of volume, breathing, pulsating, expanding, contracting through his use of colors.

If there is one thing more than another in this whole accursed tissue of false society, which makes me angry, it is the asinine stupidity which with the true phlegm of impenetrable dullness says, "Why don't the women leave!" Will you tell me where they will go and what they shall do? When the State, the legislators, has given to itself, the politicians, the utter and absolute control of the opportunity to live; when, through this precious monopoly, already the market of labor is so overstocked that workmen and workwomen are cutting each others' throats for the dear privilege of serving their lords; when girls are shipped from Boston to the south and north, shipped in carloads, like cattle, to fill the dives of New Orleans or the lumber-camp hells of my own state...
