Whitehead's panpsychism as the subjectivity of prehension

Whitehead's concept of prehension is undeniably the master principle of his process metaphysics. It is the central function of a creative universe whereby the many past occasions become a novel one. In my view, the concept of prehension is Whitehead's most original and distinctive contribution to metaphysics. It is also the very idea that prevents most contemporary philosophers from understanding or appreciating his thought.
