Context

“On the one hand, the living individual, which was at first pre-supposed as immediate, is now seen to be mediated and generated. On the other, however, the living individuality, which, on account of its first immediacy, stands in a negative attitude towards universality, sinks in the superior power of the latter. The living being dies, because it is a contradiction. Implicitly it is the universal or Kind, and yet immediately it exists as an individual only. Death shows the Kind to be the power that rules the immediate individual. For the [Pg 362] animal the process of Kind is the highest point of its vitality.” source
