On Whitehead and occasions of experience

"In either case, whether or no there be conceptual novelty, the subjective forms of the conceptual prehensions constitute the drive of the Universe, whereby each occasion precipitates itself into the future."
"The occasions originate from a common past and their objective immortality operates within a common future. Thus indirectly, via the immanence of the past and the immanence of the future, the occasions are connected."
(different occasions immanent in a common past, which is immortal in them, and makes them reciprocally immanent. But the objective immortality of the past in them is different, and two different occasions derive from different pasts)
Any occasion experiences its past as anticipating a future of which it is part, together with its contemporary environment (immanence of the contemporary world in an occasion, as a 'related'
substratum)
Antecedent environmental factors are also eliminated in the initial phase of a new occasion, as the running stream purifies itself

The very meaning of existence is to be a factor in agency, to make a difference (Plato)

Sense-perception is an abstraction (instinctive intepretation, causal efficacy and presentational immediacy, symbolism)

Higher consciousness about things is perception, inarticulate feeling when attention is dispersed is sensation (prehension).
Though everything is real, not everything is realised in a set of actual occasions.
