common during the Christian era, but was rare in pagan antiquity, he bases
his sexual ethics on the notion that procreat ion is the natural purpose of
sex. The Athenian says at one point that he would like to put into eVect ‘A
law to permit sexual intercourse only for its natural purpose, procr eation,
and to prohibit homosexual relations; to forbid the deliberate killing of a
human oVspring and the casting of seed on rocks and stone where it will
never take root and fructify’ (8. 838e). He realizes, however, that it will be
very diYcult to ensure compliance with such a law, and instead he
proposes other measures to stamp out sodomy and discourage all forms
of non-procreative intercourse (8. 836e, 841d). We have reached a point in
Plato’s thinking far distant from the arch homosexual banter which is such
a predominant feature of the Socratic dialogues.
One of the most interesting sections of the Laws is the tenth book, which
deals wit h the worship of the gods and the elimination of heresy. Impiety
arises, the Athenian says, when people do not believe that the gods exist, or
believe that they exist but do not care for the human race. As a preamble to
laws against impiety, therefore, the lawgiver must establish the existence of
the divine. The elaborate argument he presents will be considered in a later
chapter on philosophy of religion.
In the Timaeus, a dialogue whose composition probably overlapped with
that of the Laws, Plato sets out the relationship between God and the world
we live in. He returns to the traditional philosophical topic of cosmology,
taking it up at the point where Anaxagoras had, in his view, left oV
unsatisfactorily. The world of the Timaeus is not a Weld of mechanistic
causes: it is fashioned by a divinity, variously called its father, its maker,
or its craftsman (demiourgos) (28c).
Timaeus, the eponymous hero of the dialogue, is an astronomer. He
oVers to narrate to Socrates the history of the universe, from the origin of
the cosmos to the appearance of mankind. People ask, he says, whether the
world has always existed or whether it had a beginning. The answer must
be that it had a beginning, because it is visible, tangible, and corporeal, and
nothing that is perceptible by the senses is eternal and changeless in the
way that the objects of thought are (27d–28c). The divinity who fashioned
it had his eye on an eternal archetype, ‘for the cosmos is the most beautiful
of the things that have come to be, and he is the best of all causes’ (29a).
Why did he bring it into existence? Because he was good, and what is good
is utterly free from envy or selWshness (29d).
