name goes all are pretty well agreed as to the
answer; gentle and simple alike declare it to be happiness, involving,
however, in their minds on the one hand well-living, on the other hand,
well-doing. When you ask them, however, to define this happiness more
exactly, you find that opinions are divided, and the many and the
philosophers have different answers.

"But if you ask a musician or a sculptor or any man of skill, any
person, in fact, who has some special work and activity, what the chief
good is for him, he will tell you that the chief good is in the work
well done. If then man has any special work or function, we may assume
that the chief good for man {194} will be in the well-doing of that
function. What now is man's special function? It cannot be mere
living, for that he has in common with plants, and we are seeking what
is peculiar to him. The mere life of nurture and growth must therefore
be put on one side. We come next to life as sensitive to pleasure and
pain. But this man shares with the horse, the ox, and other animals.
What remains is the life of action of a reasonable being. Now of
reason as it is in man there are two parts, one obeying, one possessing
and considering. And there are also two aspects in which the active or
moral life may be taken, one potential, one actual. Clearly for our
definition of the chief good we must take the moral life in its full
actual realisation, since this is superior to the other.

"If our view thus far be correct, it follows that the chief good for
man consists in the full realisation and perfection of the life of man
as man, in accordance with the specific excellence belonging to that
life, and if there be more specific excellences than one, then in
accordance with that excellence which is the best and the most rounded
or complete. We must add, however, the qualification, 'in a rounded
life.' For one swallow does not make a summer, nor yet one day. And
so one day or some brief period of attainment is not sufficient to make
a man happy and blest."

The close relation of this to the teaching of Socrates and Plato need
hardly be insisted on, or the way in which he correlates their ideas
with his own conception of an actualised perfection.

Aristotle then proceeds to a definition of the 'specific excellence' or
virtue of man, which is to be the standard by which we decide how far
he has fully and perfectly realised the possibilities of
