and moral
chaos. Only by brooding on the moral chaos could the spirit of truth
evoke a new order; only out of the moral darkness could a new
intellectual light be made to shine. The social and personal anarchy
seemed to be a _reductio ad absurdum_ of the philosophy of nature; if
ever the philosophy of nature was to be recovered it must be through a
revision of the theory of morals. If it could be proved that the
doctrine of individualism, of isolation, which the analysis of a
Protagoras or a Gorgias had reached, was not only _unlivable_ but
unthinkable,--carried the seeds of its own destruction, theoretical as
well as practical, within {102} itself,--then the analysis of
_perception_, from which this moral individualism issued, might itself
be called to submit to revision, and a stable point of support in the
moral world might thus become a centre of stability for the
intellectual and the physical also.

By a perfectly logical process, therefore, the crisis of philosophy
produced in Greece through the moral and social chaos of the sophistic
teaching had two issues, or perhaps we may call it one issue, carried
out on the one side with a less, on the other side with a greater
completeness. The less complete reaction from sophistic teaching
attempted only such reconstruction of the moral point of view as should
recover a law or principle of general and universally cogent character,
whereon might be built anew a _moral_ order without attempting to
extend the inquiry as to a universal principle into the regions of
abstract truth or into physics. The more complete and logical
reaction, starting, indeed, from a universal principle in morals,
undertook a logical reconstruction on the recovered universal basis all
along the line of what was knowable.

To Socrates it was given to recover the lost point of stability in the
world of morals, and by a system of attack, invented by himself, to
deal in such a manner with the anarchists about him as to prepare the
way for his successors, when the time was ripe for a more extended
exposition of the new point of {103} view. Those who in succession to
him worked out a more limited theory of law, mainly or exclusively in
the world of morals, only were called the _Incomplete Socratics_.
Those who undertook to work it out through the whole field of the
knowable, the _Complete Socratics_, were the two giants of philosophy,
Plato and Aristotle.

Greek philosophy then marks with the li
