Plotinus,
Plotinos: Complete Works, v. 3
“ Do they constitute other kinds of movement than those already noticed, generation and destruction, growth and decrease, movement of displacement and alteration? Shall composition and decomposition be reduced to some one of these kinds of motion, or shall we look at this process inversely? If composition consist in approximating one thing to another, and in joining them together; and if, on the other hand, decomposition consist in separating the things which were joined, we have here only two movements of displacement, a uniting, and a separating one. ”
