La luce come simbolo della filosofia (del matricidio simbolico della filosofia)

An ancient friendship connects the metaphor of light to philosophy, a mutual need, a constant identity. From Parmenides to Heidegger, from Heraclite to Lévinas, even if within a progressive masking mechanism, the light was a sort of double for philosophy, its alter ego, its twin of placenta, so much so that, with Jacques Derrida, we can say that there is a constant "heliotropic" vocation of the entire western history of philosophy, above all of that which arises in metaphysical form. In this article we affirm that this metaphor is so primitive, so vital, that it is not only a cultural metaphor, but also a psychic and biological and even ecological metaphor. We could also define it a "primordial image" or an "archetype" imprinted within that complex process of mutual adaptation of the individual to the stimulus coming from Nature, which is repeated every time and in every man at the moment of birth, in the "coming to the light"
