Madly as Christians might love the martyr or hate the suicide,
they never felt these passions more madly than I had felt them long
before I dreamed of Christianity. Then the most difficult and
interesting part of the mental process opened, and I began to trace
this idea darkly through all the enormous thoughts of our theology.
The idea was that which I had outlined touching the optimist and
the pessimist; that we want not an amalgam or compromise, but both
things at the top of their energy; love and wrath both burning.
Here I shall only trace it in relation to ethics. But I need not
remind the reader that the idea of this combination is indeed central
in orthodox theology. For orthodox theology has specially insisted
that Christ was not a being apart from God and man, like an elf,
nor yet a being half human and half not, like a centaur, but both
things at once and both things thoroughly, very man and very God.
Now let me trace this notion as I found it.

All sane men can see that sanity is some kind of equilibrium;
that one may be mad and eat too much, or mad and eat too little.
Some moderns have indeed appeared with vague versions of progress and
evolution which seeks to destroy the MESON or balance of Aristotle.
They seem to suggest that we are meant to starve progressively,
or to go on eating larger and larger breakfasts every morning for ever.
But the great truism of the MESON remains for all thinking men,
and these people have not upset any balance except their own.
But granted that we have all to keep a balance, the real interest
comes in with the question of how that balance can be kept.
That was the problem which Paganism tried to solve: that was
the problem which I think Christianity solved and solved in a very
strange way.
