“It is just as foolish to complain that people are selfish and treacherous as it is to complain that the magnetic field does not increase unless the electric field has a curl. Both are laws of nature.”

“If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.”

“Young man, in mathematics you don't understand things. You just get used to them.”

“Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin.”

“Se la gente non crede che la matematica è semplice, è solo perché non capisce quanto è complicata la vita.”

“The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work - that is correctly to describe phenomena from a reasonably wide area. Furthermore, it must satisfy certain esthetic criteria - that is, in relation to how much it describes, it must be rather simple.”

“However, the natural symbol, without our being sufficiently conscious of the fact, is identical with the reality of the world that appears to us, for every object in the natural world is at the same time a symbolic reality to us. The psyche certainly does not use an "object" of nature as a "symbol," but rather the experience of an "object" itself is always already symbolic experience. The star or tree in us is no less real and no less symbolic than it is in outward experience. For each possibility of experience either presupposes a spiritually forming, that is to say a symbolic activity, or is identical with this. That is, everything spiritual appears to us first not just in nature but as nature; or we could formulate this just as well the other way around: everything natural, whether outward or inward, appears to us as an image, that is to say as formed spirit. We are surrounded by images, inwardly and outwardly, but at the same time formed and determined in all our experiences by the natural symbol as though by a unitary natural-spiritual reality, for our psychic system only grasps that which appears to us as the real world through the world of natural symbolism.”
