And why could all this not be fulfilled in the case of an organism composed of a moderate number of atoms only and sensitive already to the impact of… - Erwin Schrödinger

It is not possible that this unity of knowledge, feeling and choice which you call your own should have sprung into being from nothingness at a given moment not so long ago; rather this knowledge, feeling, and choice are essentially eternal and unchangeable and numerically one in all men, nay in all sensitive beings. But not in this sense — that you are a part, a piece, of an eternal, infinite being, an aspect or modification of it... For we should then have the same baffling question: which part, which aspect are you? what, objectively, differentiates it from the others? No, but, inconceiveable as it seems to ordinary reason, you — and all other conscious beings as such — are all in all. Hence, this life of yours... is, in a certain sense, the whole... This, as we know, is what the Brahmins express in that sacred, mystic formula... 'Tat tvam asi' — this is you. Or, again, in such words as 'I am in the east and in the west, I am below and above, I am this whole world.' Thus you can throw yourself flat on the ground, stretched out upon Mother Earth, with certain conviction that you are one with her and she with you … For eternally and always there is only now, one and the same now; the present is the only thing that has no end.

Not only has none of us ever experienced more than one consciousness, but there is also no trace of circumstantial evidence of this ever happening anywhere in the world. If I say that there cannot be more than one consciousness in the same mind, this seems a blunt tautology — we are quite unable to imagine the contrary...

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.
