Atomism
The notion that matter is made up of small, indivisible particles goes
back to the ancient Greeks. In the sixth century BCE, thinkers began
asking questions about what is the basic underlying reality of the
world. In view of the constant change we see in the world around us, is
there some substratum (physis, hence our word physics) that is constant?
If so, is it material or immaterial, accessible through the senses or
only through the mind, is it one or many? Over the next several
centuries, these questions were answered in several different ways. Some
believed that all was change, others that change was illusory. The
Pythagoreans thought that the physis was "number" and pioneered the
mathematical approach to nature. Their idealist approach was in stark
contrast to that of the materialists, among whom the atomists were most
prominent. Leucippus of Miletus (ca. 435 BCE) and Democritus of Abdera
(ca. 410 BCE) developed the atomic hypothesis. According to them matter
can be subdivided only to a certain point, at which only atoms (that
which cannot be cut) remain. The world is made up of atoms moving in the
void. Atoms differed from each other only in size and shape, and
different substances with their distinct qualities were made up of
different shapes, arrangements, and positions of atoms. Atoms were in
continuous motion in the infinite void and constantly collided with each
other. During these collisions they could rebound or stick together
because of hooks and barbs on their surfaces. Thus, underlying the
changes in the perceptible world, there was constancy (atoms were
neither created nor destroyed); change was caused by the combinations
and dissociations of the atoms. Democritus gave some examples of how the
atomic hypothesis could account for qualities such as color and taste
(sharp tastes are caused by sharp atoms), but on the whole atomism, like
other contemporary global theories, remained a general theory. It was
criticized by Aristotle (384-322 BCE) for some of its logical
inconsistencies[1] and for its inability to explain qualities (color,
taste, odor, etc.) that we call (after Galileo) secondary qualities.
Aristotle's matter theory was fundamentally qualitative: qualities were
built into the fundamental building blocks that made up substances. And
against the atomists' idea of a nature without design or purpose,
Aristotle constructed a natural philosophy that made nature a purposeful
agent. In the philosophical system of Epicurus (341-270 BCE), physics
was subordinated to ethics. The aim of his philosophy was to overcome
irrational fears of natural phenomena and to achieve peace of mind.
Epicurus explained natural phenomena by atomism, but he made several
modifications to the doctrine in view of Aristotle's criticisms. He
distinguished between physical and mathematical divisibility and gave
atoms weight.

Thanks, James
By the way,
Are you referring to the concept that intelligent beings
have been here before, or to the *concept* that carbon has
6e, 6n, 6p?
Any references to ancient greek knowledge would be appreciated.
