Since in this an advance into the region of the ideal is observable, Parmenides began Philosophy proper. A man now constitutes himself free from all ideas and opinions, denies their truth, and says necessity alone, Being, is the truth. This beginning is certainly still dim and indefinite, and we cannot say much of what it involves; but to take up this position certainly is to develop Philosophy proper, which has not hitherto existed. The dialectic that the transient has no truth, is implied in it, for if these determinations are taken as they are usually understood, contradictions ensue. In Simplicius (in Arist. Phys. p. 27 b.; 31 b.) we have further metaphorical images from Parmenides. “Since the utmost limit of Being is perfect, it resembles on every side the form of a well rounded sphere, which from its centre extends in all directions equally, for it can be neither larger or smaller in one part or another. There is no non-being which prevents it from attaining to the like”—from coming into unity with itself—“and there is no Being where it was devoid of Being, here more and there less. Because the all is without defect, it is in all places in the same way like itself in its determinations.” Plotinus in the passage quoted says: “He compares Being with the spherical form, because it comprehends all in itself, and Thought is not outside of this, but is contained in it.” And Simplicius says: “We must not wonder at him, for on account of the poetic form, he adopts a mythological fiction (_πλάσματος_).” It immediately strikes us that the sphere is limited, and furthermore in space, and hence another must be above it; but then the Notion of the sphere is the similarity of withholding the different, notwithstanding that even the undifferentiated must be expressed; hence this image is inconsistent.
