As we have seen being belongs to everything perceivable, it is what all perceptions have in common; the question now is, where is it perceived? Is being in the perceivedness of the object or does it belong in some way to the soul? Theaetetus’ answer to this question also gives the characteristic of how the excess is engaged with: “In my view, ousia [being] belongs to what the soul, through and by itself strives for.” (146) The soul has a direct relationship to the excess, which is one of striving.
This striving is the fundamental characteristic of the soul’s relationship to being, and implies an active reaching for something. This contrasts with perception, which Heidegger defines as something we lose ourselves in, in perceiving we accept and have beings. (148) Striving, by definition, does not have the object it strives for, as an activity it is essentially incomplete, never-ending; if we achieve the object of our striving then it comes to an end.
Our immediate perception of beings, things, is non-regarding and non-conceptual. We do not occupy ourselves with beings as such, i.e. their being-blue or being-audible, nor do we grasp their being conceptually, i.e. their being-different, one etc. From this it is clear that in a perception we have beings before us, but not being, the excess. Our connection to being is one of striving by the soul, which carries us along, in a relationship which is also called eros.
