By introducing 'drives' into a Sartrean framework, 'being-in-itself' is interpreted as 'Nature as such', wherein instincts dominate. Being-for-itself, on the contrary, has an ontological nature diametrically opposed to this former - indeed, in the latter realm, through a fundamental process of 'nihilation' (Sartre's 'freedom') consciousness perpetually flees itself by transcending towards the world. However, a kernel of (our) nihilated Nature is left at the heart of this process, in the form of 'original facticity' that we here name drives. Drives are the original feelings and urges of a freed Nature that simply are there; they are the fundamental forces that consciousness qua freedom always has to deal with. Drives, in addition, can be nihilated in their own turn, onto a reflective, irreal plane, whereby they take the form of value. This means Sartre's notion of ontological desire is always made up of two necessary components: drives and value.
