From "Thoughts on Amazing Stories"

By Barry N. Malzberg.

Science fiction, as John W. Campbell once pointed out expansively, may indeed outdo all of the so-called mainstream because it gathers in all of time and space . . . but science fiction as it has evolved is an extraordinarily rigorous and delimiting medium. Like the canon and the fugue, the sonnet and the sonata, like haiku, it has its rules, and the control of those rules is absolute. Extrapolative elements, cultural interface, characteriological attempt to resolve the conflicts between the two: this is science fiction.

The fact pervades all the decades after about 1935: no one could publish science fiction unless exposed to a great deal of it; virtually everyone who has ever sold a story has a sophisticated reader’s background in the form, usually acquired just before or around adolescence. At the underside, this has led to parochialism, incestuousness, and the preciosity of decadence (and there has been too much). In the end it may even be these qualities which finish science fiction off, make its most sophisticated and advanced examples increasingly inaccessible to the larger reading audience.

From Schiller's letters on aesthetics

"No doubt the artist is the child of his time, but unhappy for him if he is its disciple or even its favorite! Let a beneficent deity carry off in good time the suckling from the breast of its mother, let it nourish him on the milk of a better age, and suffer him to grow up and arrive at virility under the distant sky of Greece. When he has attained manhood, let him come back, presenting a face strange to his own age; let him come, not to delight it with his apparition, but rather to purify it, terrible as the son of Agamemnon. He will, indeed, receive his matter from the present time, but he will borrow the form from a nobler time and even beyond all time, from the essential, absolute, immutable unity. There, issuing from the pure ether of its heavenly nature, flows the source of all beauty, which was never tainted by the corruptions of generations or of ages, which roll along far beneath it in dark eddies."

From Schiller's letters on aesthetics

"But the state is an organization which fashions itself through itself and for itself, and for this reason it can only be realized when the parts have been accorded to the idea of the whole. The state serves the purpose of a representative, both to pure ideal and to objective humanity, in the breast of its citizens, accordingly it will have to observe the same relation to its citizens in which they are placed to it; and it will only respect their subjective humanity in the same degree that it is ennobled to an objective existence. If the internal man is one with himself he will be able to rescue his peculiarity, even in the greatest generalization of his conduct, and the state will only become the exponent of his fine instinct, the clearer formula of his internal legislation. But if the subjective man is in conflict with the objective, and contradicts him in the character of a people, so that only the oppression of the former can give victory to the latter, then the state will take up the severe aspect of the law against the citizen, and in order not to fall a sacrifice, it will have to crush under foot such a hostile individuality without any compromise."

From Schiller's letters on aesthetics

"It may be urged that every individual man carries within himself, at least in his adaptation and destination, a purely ideal man. The great problem of his existence is to bring all the incessant changes of his outer life into conformity with the unchanging unity of this ideal. This pure ideal man, which makes itself known more or less clearly in every subject, is represented by the state, which is the objective, and, so to speak, canonical form in which the manifold differences of the subjects strive to unite. Now two ways present themselves to the thought in which the man of time can agree with the man of idea, and there are also two ways in which the state can maintain itself in individuals. One of these ways is when the pure ideal man subdues the empirical man, and the state suppresses the individual, or again when the individual becomes the state, and the man of time is ennobled to the man of idea.

"[...] education will always appear deficient when the moral feeling can only be maintained with the sacrifice of what is natural; and a political administration will always be very imperfect when it is only able to bring about unity by suppressing variety."

From Schiller's letters on aesthetics

"But as a moral being he cannot possibly rest satisfied with a political condition forced upon him by necessity, and only calculated for that condition; and it would be unfortunate if this did satisfy him. In many cases man shakes off this blind law of necessity, by his free spontaneous action, of which among many others we have an instance, in his ennobling by beauty and suppressing by moral influence the powerful impulse implanted in him by nature in the passion of love. Thus, when arrived at maturity, he recovers his childhood by an artificial process, he founds a state of nature in his ideas, not given him by any experience, but established by the necessary laws and conditions of his reason, and he attributes to this ideal condition an object, an aim, of which he was not cognizant in the actual reality of nature. He gives himself a choice of which he was not capable before, and sets to work just as if he were beginning anew, and were exchanging his original state of bondage for one of complete independence, doing this with complete insight and of his free decision. He is justified in regarding this work of political thraldom as non-existing, though a wild and arbitrary caprice may have founded its work very artfully; though it may strive to maintain it with great arrogance and encompass it with a halo of veneration. For the work of blind powers possesses no authority before which freedom need bow, and all must be made to adapt itself to the highest end which reason has set up in his personality."
