OF THE NATURE OF GENERATIVE SEED.
ARISTOTLE says, that seed is that thing which contains in
itself a power of moving, whereby it is enabled to produce
a being like unto that from whence it was emitted. Pythagoras, that seed is the sediment of that which nourisheth
us, the froth of the purest blood, of the same nature as
the blood and marrow of our bodies. Alcmaeon, that it is
a part of the brain. Plato, that it is the deflux of the
spinal marrow. Epicurus, that it is a fragment torn from
the body and soul. Democritus, that it proceeds from all
the parts of the body, and chiefly from the principal parts.
as the flesh and muscles.
