the seventh letter   

such an impulse unaided nor make myself responsible for such a deep
and real disgrace, if the reports brought by anyone were really
true. So blindfolding myself with this reflection, I set out, with
many fears and with no very favourable anticipations, as was natural
enough. However, I went, and my action on this occasion at any rate
was really a case of "the third to the Preserver," for I had the
good fortune to return safely; and for this I must, next to the God,
thank Dionysios, because, though many wished to make an end of me,
he prevented them and paid some proper respect to my situation.
On my arrival, I thought that first I must put to the test the
question whether Dionysios had really been kindled with the fire of
philosophy, or whether all the reports which had come to Athens were
empty rumours. Now there is a way of putting such things to the test
which is not to be despised and is well suited to monarchs, especially
to those who have got their heads full of erroneous teaching, which
immediately my arrival I found to be very much the case with
Dionysios. One should show such men what philosophy is in all its
extent; what their range of studies is by which it is approached,
and how much labour it involves. For the man who has heard this, if he
has the true philosophic spirit and that godlike temperament which
makes him a kin to philosophy and worthy of it, thinks that he has
been told of a marvellous road lying before him, that he must
forthwith press on with all his strength, and that life is not worth
living if he does anything else. After this he uses to the full his
own powers and those of his guide in the path, and relaxes not his
efforts, till he has either reached the end of the whole course of
study or gained such power that he is not incapable of directing his
steps without the aid of a guide. This is the spirit and these are the
thoughts by which such a man guides his life, carrying out his work,
whatever his occupation may be, but throughout it all ever cleaving to
philosophy and to such rules of diet in his daily life as will give
him inward sobriety and therewith quickness in learning, a good
memory, and reasoning power; the kind of life which is opposed to this
he consistently hates. Those who have not the true philosophic temper,
but a mere surface colouring of opinions penetrating, like sunburn,
only skin deep, when they see how great the range of studies is, how
much labour is involved in it, and how necessary to the pursuit it
is to have an orderly regulation of the daily life, come to the
conclusion that the thing is difficult and impossible for them, and
are actually incapable of carrying out the course of study; while some
of them persuade themselves that they have sufficiently studied the
whole matter and have no need of any further effort. This is the
sure test and is the safest one to apply to those who live in luxury
and are incapable of continuous effort; it ensures that such a man
shall not throw the blame upon his teacher but on himself, because
he cannot bring to the pursuit all the qualities necessary to it. Thus
it came about that I said to Dionysios what I did say on that
occasion.
I did not, however, give a complete exposition, nor did Dionysios
ask for one. For he professed to know many, and those the most
important, points, and to have a sufficient hold of them through
instruction given by others. I hear also that he has since written
about what he heard from me, composing what professes to be his own
handbook, very different, so he says, from the doctrines which he
heard from me; but of its contents I know nothing; I know indeed
that others have written on the same subjects; but who they are, is
more than they know themselves. Thus much at least, I can say about
all writers, past or future, who say they know the things to which I
devote myself, whether by hearing the teaching of me or of others,
or by their own discoveries-that according to my view it is not
possible for them to have any real skill in the matter. There
neither is nor ever will be a treatise of mine on the subject. For
it does not admit of exposition like other branches of knowledge;
but after much converse about the matter itself and a life lived
