characterized the Greeks. The philosopher is no longer living in the
unseen, nor is he sent by an oracle to convince mankind of ignorance;
nor does he regard knowledge as a system of ideas leading upwards by
regular stages to the idea of good. The eagerness of the pursuit has
abated; there is more division of labour and less of comprehensive
reflection upon nature and human life as a whole; more of exact
observation and less of anticipation and inspiration. Still, in the
altered conditions of knowledge, the parallel is not wholly lost; and
there may be a use in translating the conception of Plato into the
language of our own age. The philosopher in modern times is one who
fixes his mind on the laws of nature in their sequence and connexion,
not on fragments or pictures of nature; on history, not on controversy;
on the truths which are acknowledged by the few, not on the opinions
of the many. He is aware of the importance of 'classifying according to
nature,' and will try to 'separate the limbs of science without breaking
them' (Phaedr.). There is no part of truth, whether great or small,
which he will dishonour; and in the least things he will discern the
greatest (Parmen.). Like the ancient philosopher he sees the world
pervaded by analogies, but he can also tell 'why in some cases a single
instance is sufficient for an induction' (Mill's Logic), while in
other cases a thousand examples would prove nothing. He inquires into
a portion of knowledge only, because the whole has grown too vast to be
embraced by a single mind or life. He has a clearer conception of the
divisions of science and of their relation to the mind of man than was
possible to the ancients. Like Plato, he has a vision of the unity of
knowledge, not as the beginning of philosophy to be attained by a study
of elementary mathematics, but as the far-off result of the working
of many minds in many ages. He is aware that mathematical studies are
preliminary to almost every other; at the same time, he will not reduce
all varieties of knowledge to the type of mathematics. He too must have
a nobility of character, without which genius loses the better half
of greatness. Regarding the world as a point in immensity, and each
individual as a link in a never-ending chain of existence, he will not
think much of his own life, or be greatly afraid of death.

Adeimantus objects first of all to the form of the Socratic reasoning,
thus showing that Plato is aware of the
