“What I criticize under the name Utopian engineering recommends the reconstruction of society as a whole, i.e. very sweeping changes whose practical consequences are hard to calculate, owing to our limited experiences. It claims to plan rationally for the whole of society, although we do not possess anything like the factual knowledge which would be necessary to make good such an ambitious claim.”
― Karl R. Popper, The Open Society and Its Enemies

“It is important for long-range stability that peaceful countries be well armed and well organized in self-defense.”
― Freeman Dyson, Disturbing the Universe

“We must regard science, then, from three points of view. First, it is the free activity of man's divine faculties of reason and imagination. Secondly, it is the answer of the few to the demands of the many for wealth, comfort and victory, gifts which it will grant only in exchange for peace, security and stagnation. Finally it is man's gradual conquest, first of space and time, the of matters as such, then of his own body and those of other living beings, and finally the subjugation of the dark and evil elements in his own soul.”
― Freeman Dyson, The Scientist as Rebel

“For my part I had rather be damned with Plato and Lord Bacon, than go to Heaven with Paley and Malthus. But it is a mistake to suppose that I dedicate my poetical compositions solely to the direct enforcement of reform, or that I consider them in any degree as containing a reasoned system on the theory of human life. Didactic poetry is my abhorrence; nothing can be equally well expressed in prose that is not tedious and supererogatory in verse. My purpose has hitherto been simply to familiarise the highly refined imagination of the more select classes of poetical readers with beautiful idealisms of moral excellence; aware that until the mind can love, and admire, and trust, and hope, and endure, reasoned principles of moral conduct are seeds cast upon the highway of life which the unconscious passenger tramples into dust, although they would bear the harvest of his happiness. Should I live to accomplish what I purpose, that is, produce a systematical history of what appear to me to be the genuine elements of human society, let not the advocates of injustice and superstition flatter themselves that I should take Æschylus rather than Plato as my model.”
