The primary and exclusive datum is self-consciousness, which, although divided [dirimiert] into self and other, soul and lived body [Leib], I and world, inner and outer, is nonetheless, polarity [Gegensätzlichkeit] and articulateness [Gegliedertheit] in one. But self-consciousness experiences itself in the play and counter-play of its constitutive factors, that is, as something alive [ein Lebendiges]. This aliveness is the basic constitution. (ST, p. 8)
