Erwin Schrödinger Quotes

"It seems plain and self-evident, yet it needs to be said: the isolated knowledge obtained by a group of specialists in a narrow field has in itself no value whatsoever, but only in its synthesis with all the rest of knowledge and only inasmuch as it really contributes in this synthesis toward answering the demand, "Who are we?

We must therefore not be discouraged by the difficulty of interpreting life by the ordinary laws of physics. For that is just what is to be expected from the knowledge we have gained of the structure of living matter. We must also be prepared to find a new type of physical law prevailing in it. Or are we to term it a non-physical, not to say a super-physical, law?

Dejando de lado la metáfora, pienso que la filosofía de los antiguos griegos nos atrae hoy porque nunca antes o desde entonces, en ningún lugar del mundo, se ha establecido nada parecido a su altamente avanzado y articulado sistema de conocimiento y especulación sin la fatídica división que nos ha estorbado durante siglos y que ha llegado a hacerse insufrible en nuestros días.

However insignificant the frictional and heating effects in a clock may be from the practical point of view, there can be no doubt that the second attitude, which does not neglect them, is the more fundamental one, even when we are faced with the regular motion of a clock that is driven by a spring. For it must not be believed that the driving mechanism really does away with the statistical nature of the process. The true physical picture includes the possibility that even a regularly going clock should all at once invert its motion and, working backward, rewind its own spring – at the expense of the heat of the environment.

When a system that is not alive is isolated or placed in a uniform environment, all motion usually comes to a standstill very soon as a result of various kinds of friction; differences of electric or chemical potential are equalized, substances which tend to form a chemical compound do so, temperature becomes uniform by heat conduction.

In physics we have dealt hitherto only with periodic crystals. To a humble physicist's mind, these are very interesting and complicated objects; they constitute one of the most fascinating and complex material structures by which inanimate nature puzzles his wits. Yet, compared with the aperiodic crystal, they are rather plain and dull. The difference in structure is of the same kind as that between an ordinary wallpaper in which the same pattern is repeated again and again in regular periodicity and a masterpiece of embroidery, say a Raphael tapestry, which shows no dull repetition, but an elaborate, coherent, meaningful design traced by the great master.

The spread, both in and width and depth, of the multifarious branches of knowledge by during the last hundred odd years has confronted us with a queer dilemma. We feel clearly that we are only now beginning to acquire reliable material for welding together the sum total of all that is known into a whole; but, on the other hand, it has become next to impossible for a single mind fully to command more than a small specialized portion of it. I can see no other escape from this dilemma (lest our true who aim be lost for ever) than that some of us should venture to embark on a synthesis of facts and theories, albeit with second-hand and incomplete knowledge of some of them -and at the risk of making fools of ourselves.

Nimm an, du sitzest in einer Hochalpenlandschaft auf einer Bank am Wege. Rings um dich her Grashalden, mit Felsblöcken durchsprengt, am Talhang gegenüber ein Geröllfeld mit niedrigem Erlengestrüpp. Steil geböschtes Waldgebirge zu beiden Seiten des Tals bis hoch hinauf an die baumlosen Almmatten; und vor dir vom Talgrund aufsteigend der gewaltige firngekrönte Hochgipfel, dessen weiche Schneelenden und scharfkantige Felsgrate jetzt eben der letzte Strahl der scheidenden Sonne in zartestes Rosenrot taucht, wundervoll abgehoben von dem durchsichtig klaren, blaßblauen Firmament.

All das, was dein Auge sieht, ist - nach der bei uns gewöhnlichen Auffassung - mit geringen Veränderungen Jahrtausende lang v o r dir dagewesen. Über ein Weilchen — nicht lange — wirst du nicht mehr sein, und Wald, Fels und Himmel werden Jahrtausende n a c h dir noch unverändert dastehen.

Was ist's, das dich so plötzlich aus dem Nichts hervorgerufen, um dieses Schauspiel, das deiner nicht achtet, ein Weilchen zu genießen? Alle Bedingungen für dein Sein sind fast so alt wie der Fels. Jahrtausende lang haben Männer gestrebt, gelitten und gezeugt, haben Weiber unter Schmerzen geboren. Vor hundert Jahren vielleicht saß ein anderer an dieser Stelle, blickte gleich dir, Andacht und Wehmut im Herzen, auf zu den verglühenden Firnen. Er war vom Mann gezeugt, vom Weib geboren gleich dir. Er fühlte Schmerz und kurze Freude wie du. W a r es ein anderer? Warst du es nicht selbst? Was ist dies dein Selbst? Welche Bedingung mußte hinzutreten, damit dies Erzeugte du wurdest, gerade du, und nicht — ein anderer? Welchen klar faßbaren, n a t u r w i s s e n s c h a f t l i c h e n Sinn soll denn dieses „ein anderer“ eigentlich haben? Hätte sie, die jetzt deine Mutter ist, einem anderen beigewohnt und mit ihm einen Sohn gezeugt, und dein Vater desgleichen, wärest d u geworden? Oder lebtest du in ihnen, in deines Vaters Vater... schon seit Jahrtausenden? Und wenn auch dies, warum bist du nicht dein Bruder, dein Bru

To give the statement life and colour, let me anticipate what will be explained in much more detail later, namely, that the most essential part of a living cell – the chromosome fibre – may suitably be called an aperiodic crystal.

Not one word is said here of acausality, wave mechanics, indeterminacy relations, complementarity, … etc. Why doesn’t he talk about what he knows instead of trespassing on the professional philosopher’s preserves? Ne sutor supra crepidam. On this I can cheerfully justify myself: because I do not think that these things have as much connection as is currently supposed with a philosophical view of the world.

The difference in structure is of the same kind as that between an ordinary wallpaper in which the same pattern is repeated again and again in regular periodicity and a masterpiece of embroidery, say a Raphael tapestry, which shows no dull repetition, but an elaborate, coherent, meaningful design traced by the great master.

The task is ... not so much to see what no one has yet seen; but to think what nobody has yet thought, about that which everybody sees.

The plurality that we perceive is only an appearance; it is not real. Vedantic philosophy... has sought to clarify it by a number of analogies, one of the most attractive being the many-faceted crystal which, while showing hundreds of little pictures of what is in reality a single existent object, does not really multiply that object.

The scientific picture of the real world around me is very deficient. It gives a lot of factual information... [but] it cannot tell us a word about red and blue, bitter and sweet, physical pain and physical delight; it knows nothing of beautiful and ugly, good or bad, God and eternity. So, in brief, we do not belong to this material world that science constructs for us... the scientific worldview contains of itself... not a word about our own ultimate scope or destination.

Thus we have come to the conclusion that an organism and all the biologically relevant processes that it experiences must have an extremely ‘many-atomic’ structure and must be safeguarded against haphazard, ‘single-atomic’ events attaining too great importance. That, the ‘naïve physicist’ tells us, is essential, so that the organism may, so to speak, have sufficiently accurate physical laws on which to draw for setting up its marvellously regular and well-ordered working.
