Quotes from Erwin Schrodinger

The physicist is familiar with the fact that the classical laws of physics are modified by quantum theory, especially at low temperature. There are many instances of this. Life seems to be one of them, a particularly striking one. Life seems to be orderly and lawful behaviour of matter, not based exclusively on its tendency to go over from order to disorder, but based partly on existing order that is kept up.

In order to be suitable material for the work of natural selection, mutations must be rare events, as they actually are. If they were so frequent that there was a considerable chance of, say, a dozen of different mutations occurring in the same individual, the injurious ones would, as a rule, predominate over the advantageous ones and the species, instead of being improved by selection, would remain unimproved, or would perish.

The second may well be beyond human understanding.

some species or even large groups seem to have reached the end of their evolutionary possibilities a very long time ago, yet they have not died out, but have remained unchanged, or without significant change, for many millions of years.

There is a difference between a shaky or out-of-focus photograph and a snapshot of clouds and fog banks

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 deficient. It gives a lot of factual information, puts all our experience in a magnificently consistent order. But it is ghastly silent about all and sundry that is really near to our heart, that really matters to us. 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.

To the physicist – but only to him – I could hope to make my view clearer by saying: The living organism seems to be a macroscopic system which in part of its behaviour approaches to that purely mechanical (as contrasted with thermodynamical) conduct to which all systems tend, as the temperature approaches the absolute zero and

To distinguish between the possession of an organ and the urge to use it and to increase its skill by practice, to regard them as two different characteristics of the organism in question, would be an artificial distinction, made possible by an abstract language but having no counterpart in nature.

What an organism feeds upon is negative entropy. Or, to put it less paradoxically, the essential thing in metabolism is that the organism succeeds in freeing itself from all the entropy it cannot help producing while alive.

MIGUEL DE UNAMUNO

How would we express in terms of the statistical theory the marvellous faculty of a living organism, by which it delays the decay into thermodynamical equilibrium (death)? We said before: 'It feeds upon negative entropy', attracting, as it were, a stream of negative entropy upon itself, to compensate the entropy increase it produces by living and thus to maintain itself on a stationary and fairly low entropy level.

THE STRIKING CONTRAST

THE STRIKING CONTRAST In biology we are faced with an entirely different situation.

Becoming is conscious, being unconscious.

The reason why our sentient, percipient and thinking ego is met nowhere within our scientific world picture can easily be indicated in seven words: because it is itself that world picture.

A mathematical truth is timeless, it does not come into being when we discover it.

Next to want, boredom has become the worst scourge in our lives.

Dutchman de Vries discovered that in the offspring even of thoroughly pure-bred stocks, a very small number of individuals, say two or three in tens of thousands, turn up with small but 'jump-like' changes, the expression 'jump-like' not meaning that the change is so very considerable, but that there is a discontinuity inasmuch as there are no intermediate forms between the unchanged and the few changed. De Vries called that a mutation.

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.

Uma verdade matemática é intemporal, não ganha existência quando a descobrimos. Contudo, sua descoberta é um evento bem real, pode ser uma emoção, como um grande presente de uma fada.

Instead of filling a gap by guesswork, genuine science prefers to put up with it; and this, not so much from conscientious scruples about telling lies, as from the consideration that, however irksome the gap may be, its obliteration by a fake removes the urge to seek after a tenable answer. So efficiently may attention be diverted that the answer is missed even when, by good luck, it comes close at hand.

The great thing was to form the idea that this one thing – mind or world – may well be capable of other forms of appearance that we cannot grasp and that do not imply the notions of space and time. This means an imposing liberation from our inveterate prejudice. There probably are other orders of appearance than the space-time-like. It was, so I believe, Schopenhauer who first read this from Kant.

The world is given to me only once, not one existing and one perceived. Subject and object are only one.
