The subversive character of truth inflicts upon thought an imperative quality. Logic centers on judgments which are, as demonstrative propositions, imperatives, - the predicative "is” implies an "ought.” ... Verification of the proposition involves a process in fact as well as in thought: (S) must become that which it is. The categorical statement thus turns into a categorical imperative; it does not state a fact but the necessity to bring about a fact. For example, it could be read as follows: man is not (in fact) free, endowed with inalienable rights, etc., but he ought to be.

As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.
Arthur Schopenhauer
It is therefore, the interest of all, that every one, from birth, should be well educated, physically and mentally, that society may be improved in its character, - that everyone should be beneficially employed, physically and mentally, that the greatest amount of wealth may be created, and knowledge attained, - that everyone should be placed in the midst of those external circumstances that will produce the greatest number of pleasurable sensations, through the longest life, that man may be made truly intelligent, moral and happy, and be thus prepared to enter upon the coming Millennium.
Robert Owen
It appears to general observation, that revolutions create genius and talents; but those events do no more than bring them forward. There is existing in man, a mass of sense lying in a dormant state, and which, unless something excites it to action, will descend with him, in that condition, to the grave. As it is to the advantage of society that the whole of its faculties should be employed, the construction of government ought to be such as to bring forward, by a quiet and regular operation, all that extent of capacity which never fails to appear in revolutions.
Thomas Paine
He [the artist in general] ought to have 'these powerful organs of expression' - colour and chiaroscuro - entirely at his command, that he may use them in every possible form, as well as that he may do with the most perfect freedom; therefore, whether he wishes to make the subject of a joyous, solemn, or meditative character, by flinging over it the cheerful aspect which the sun bestows, by a proper disposition of shade, or by the appearances that beautify its arising or its setting, a true "General Effect" should never be lost sight of.
John Constable
Over the years, I have become convinced that Hellenism as a culture represents not a static condition of uniform sublimity mysteriously achieved and maintained as an effect of some racial advantage. Rather it should be understood as an evolving process, governed by a dynamic of change, as both language and thought underwent transformational alteration caused by a transition from orality to literacy. The instrument of change is discerned to be the invention of the Greek alphabet, at a quite late stage in the history of developing cultures.
