Arche and Apeiron in Early Presocratic Philosophy

Metaphysical speculation began, long before it was so named, among the presocratic Greeks as an enquiry into cosmology and first principles from two utterly disparate perspectives. The first of these, propounded by Herakleitos, noted the incessant flux (panta rhei) which characterises phenomena; the second, advanced by his contemporary Parmenides, taught the doctrine of a single immutable substance. These rivalling perspectives endure to this day: they announce one of the basic themes on which metaphysics since then has strung up an immense set of variations.

Behind both stands the concept of arche, a term introduced into philosophical discourse by Anaximandros, rendered into English …show more content…

I like to think of this as an eminently ‘metaphysical misgiving’, whose issue was an intuition that an arche cannot be matter at all; that indeterminacy (apeira) is surely the condition at the opposite pole from determinacy and that without this contrast, the very condition of being is inexplicable — for as much as genesis presupposes agency, it cannot work on matter already formed. Impossible to know what Anaximandros’ thought process might have been: yet he worked within a tradition which kept before his eyes the notion of a continuum of formed matter throughout the intelligible cosmos, in which Eros functioned as the principle of fecundity. But Eros transforms: it cannot have escaped him, with his predilections. Hence he must seek the formless, the unbounded, the passive, inactive, neutral, atemporal and nonspatial in which determinacy is latent but not explicit — in short, the …show more content…

Thales seems still to have taught that the earth is flat (somewhat like a tambourine) and floats on water — presumably the ‘real’ ocean of which Plato speaks in the Critias. His successor considered this an unsatisfactory theory because it opens itself to infinite regress. Consequently Anaximandros replaced it with a spherical earth hanging motionlessly and unsupported in the midst of space and surrounded by the concentric shells (wheel rims) occupied respectively by sun, moon and the stars. His reply to such critical objections as, what is there to prevent the earth from hurtling aimlessly hither and thither, was: What is to prevent the earth from sitting still? Motion requires a charge (impetus or attraction), while ‘hurtling’ (i.e. falling) implies directionality, but as the earth occupies the exact geometric centre of the heavens, all directions are equal, hence all difference between up and down and sideways becomes
