[Chernobyl has strengthened the] growing impulse to escape from the nightmare of peace being dependent upon the contemplation of horrific and mutual carnage. Events have now so developed that this aspiration can at last be rationally, logically and – I dare to add – patriotically seized by the people of the United Kingdom if they will use their votes to do so.
A more detailed, but still uncontroversial comprehensive, definition is that philosophy is rationally critical thinking, of a more or less systematic kind about the general nature of the world (metaphysics or theory of existence), the justification of belief (epistemology or theory of knowledge), and the conduct of life (ethics or theory of value). Each of these three elements...
At the present time I seem to be thinking rationally again in the style that is characteristic of scientists. However this is not entirely a matter of joy as if someone returned from physical disability to good physical health. One aspect of this is that rationality of thought imposes a limit on a person's concept of his relation to the cosmos.john forbes nash
We must not suppose that, because a man is a rational animal, he will, therefore, always act rationally; or, because he has such or such a predominant passion, that he will act invariably and consequentially in pursuit of it. No, we are complicated machines; and though we have one main spring that gives motion to the whole, we have an infinity of little wheels, which, in their turns, retard, precipitate, and sometime stop that motion.stanhope, philip, 4th earl of chesterfield
While most people can talk rationally about kernel design and portability, the issue of free-ness is 100% emotional.andrew s. tanenbaum
Someone who has thought rationally and deeply about how the body works is likely to arrive at better ideas about how to be healthy than someone who has followed a hunch. Medicine presupposes a hierarchy between the confusion the layperson will be in about what is wrong with him, and the more accurate knowledge available to doctors reasoning logically. … At the heart of Epicureanism is the thought that we are as bad at answering the question “What will make me happy?” as “What will make me healthy?” … Our souls do not spell out their troubles.Alain de Botton
There may be occasions when it is best to behave irrationally, but whether there are should be decided rationally.i. j. good
It may indeed prove to be far the most difficult and not the least important task for human reason rationally to comprehend its own limitations. It is essential for the growth of reason that as individuals we should bow to forces and obey principles which we cannot hope fully to understand, yet on which the advance and even the preservation of civilization depend.friedrich hayek
Once the philosophical foundation of democracy has collapsed, the statement that dictatorship is bad is rationally valid only for those who are not its beneficiaries, and there is no theoretical obstacle to the transformation of this statement into its opposite.max horkheimer
I forgot, being too interested myself, that he’s a king, and does not see things rationally, but as a king.ursula k. le guin
Mark how fleeting and paltry is the estate of man - yesterday in embryo, tomorrow a mummy or ashes. So for the hairsbreadth of time assigned to thee, live rationally, and part with life cheerfully, as drops the ripe olive, extolling the season that bore it and the tree that matured it.marcus aurelius
Till women are more rationally educated, the progress in human virtue and improvement in knowledge must receive continual checks.mary wollstonecraft
Wherever people prefer to call upon "offenses against moral sentience", upon "moral terms" rather than adhere to one's rationally derived scientific criminological approach [dividing irrational, ethnocentric "moral offenses" from actual crimes], one is fully justified in speaking of prejudice's total victory over reason.
The last level of metaphor in the Alice books is this: that life, viewed rationally and without illusion, appears to be a nonsense tale told by an idiot mathematician. At the heart of things science finds only a mad, never-ending quadrille of Mock Turtle Waves and Gryphon Particles. For a moment the waves and particles dance in grotesque, inconceivably complex patterns capable of reflecting on their own absurdity.martin gardner
There exists no third principle for the organisation of the economics process which can be rationally chosen to achieve any desirable ends, in addition to either a functioning market in which nobody can conclusively determine how well-off particular groups or individuals will be, or a central direction where a group organised for power determines it.friedrich hayek
The first consequence of the principle of bounded rationality is that the intended rationality of an actor requires him to construct a simplified model of the real situation in order to deal with it. He behaves rationally with respect to this model, and such behavior is not even approximately optimal with respect to the real world. To predict his behavior we must understand the way in which this simplified model is constructed, and its construction will certainly be related to his psychological properties as a perceiving, thinking, and learning animal.
