Quotes on Theoretical

Economics was like psychology, a pseudoscience trying to hide that fact with intense theoretical hyperelaboration. And gross domestic product was one of those unfortunate measurement concepts, like inches or the British thermal unit, that ought to have been retired long before.

I see anarchism as the theoretical ideal to which we are all gradually evolving to a point where everybody can tell the truth to everybody else and nobody can get punished for it. That can only happen without hierarchy and without people having the authority to punish other people.

Fiction and essays can create empathy for the theoretical stranger.

I may be just an empty flesh terminal reliant on technology for all my ideas, memories and relationships, but I am confident that all of that everything that makes me a unique human being is still out there somewhere, safe in a theoretical storage space owned by giant, multinational corporations.

If the facts don't fit the theory, change the facts.

Medicine is a social science, and politics is nothing else but medicine on a large scale. Medicine, as a social science, as the science of human beings, has the obligation to point out problems and to attempt their theoretical solution: the politician, the practical anthropologist, must find the means for their actual solution. The physicians are the natural attorneys of the poor, and social problems fall to a large extent within their jurisdiction.

The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.

Any work of science, no matter what its point of departure, cannot become fully convincing until it crosses the boundary between the theoretical and the experimental: Experimentation must give way to argument, and argument must have recourse to experimentation.

The book, as it stands, seems to me to be one of the most frightful muddles I have ever read, with scarcely a sound proposition in it beginning with page 45 [Hayek provided historical background up to page 45; after that came his theoretical model], and yet it remains a book of some interest, which is likely to leave its mark on the mind of the reader. It is an extraordinary example of how, starting with a mistake, a remorseless logician can end up in bedlam.

In my own view, some advice about what should be known, about what technical education should be acquired, about the intense motivation needed to succeed, and about the carelessness and inclination toward bias that must be avoided is far more useful than all the rules and warnings of theoretical logic.

When you work on something that combines both the spectacular and the relatable, the hyperreal and the real, it suddenly can become supernatural. The hypothetical and the theoretical can become literal.

Is it needy? It's not. We don't need each other. We just really, really enjoy each other. And we're good together. We're good people together. And I have the funniest feeling. I can really, truly touch this all, this happiness and the sadness too, I can trace all of it with my fingers. It isn't theoretical or distant. This feels like me. This is me. I love him, and, for the first time in a relationship, I also like me. Every time he says "I love you," I answer, "I believe you.

The release of atomic energy has not created a new problem. It has merely made more urgent the necessity of solving an existing one.

Judicial execution can never cancel or remove the atrocity it seeks to punish; it can only add a second atrocity to the original one ... So long as one sees killing as wrong there is no need to waste time with the deterrent argument, since it would be nonsense to try to prevent a theoretical evil in the future by perpetrating an actual one in the present.

Isolated facts and experiments have in themselves no value, however great their number may be. They only become valuable in a theoretical or practical point of view when they make us acquainted with the law of a series of uniformly recurring phenomena, or, it may be, only give a negative result showing an incompleteness in our knowledge of such a law, till then held to be perfect.

Once the inner connection is grasped, all theoretical belief in the permanent necessity of existing conditions collapses before their collapse in practice -- Letter to Ludwig Kugelmann (July 11, 1868)

Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of invention. ... [Do not] share the opinion of those narrow minds who disdain everything in science which has not an immediate application. ... A theoretical discovery has but the merit of its existence: it awakens hope, and that is all. But let it be cultivated, let it grow, and you will see what it will become.

The ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.

History shows that the human mind, fed by constant accessions of knowledge, periodically grows too large for its theoretical coverings, and bursts them asunder to appear in new habiliments, as the feeding and growing grub, at intervals, casts its too narrow skin and assumes another.

I am now convinced that theoretical physics is actually philosophy.

I need scarcely say that the beginning and maintenance of life on earth is absolutely and infinitely beyond the range of all sound speculation in dynamical science. The only contribution of dynamics to theoretical biology is absolute negation of automatic commencement or automatic maintenance of life.
