the life of the philosopher, the life of scientific and philosophic contemplation

Pleasure is, therefore, a necessary element in the best life, but it is
not the whole of it nor the principal ingredient. The value of a life
depends upon the nature and worth of the activity which it involves;
given the maximum of full free action, the maximum of pleasure necessary
follows. But on what sort of life is such activity possible? This leads
us back to the question, What is happiness? In what life can man find
the fullest satisfaction for his desires? To this question Aristotle
gives an answer which cannot but surprise us after what has preceded.
True Happiness, great satisfaction, cannot be found by man in any form
of "practical" life, no, not in the fullest and freest exercise possible
of the "moral virtues," not in the life of the citizen or of the
great soldier or statesman. To seek it there is to court failure and
disappointment. It is to be found in the life of the onlooker, the
disinterested spectator; or, to put it more distinctly, "in the life of
the philosopher, the life of scientific and philosophic contemplation."
The highest and most satisfying form of life possible to man is "the
contemplative life"; it is only in a secondary sense and for those
incapable of their life, that the practical or moral ideal is the best.
It is time that such a life is not distinctively human, but it is the
privilege of man to partake in it, and such participation, at however
rare intervals and for however short a period, is the highest Happiness
which human life can offer. All other activities have value only because
and in so far as they render _this_ life possible.

But it must not be forgotten that Aristotle conceives of this life as
one of intense activity or energising: it is just this which gives it
its supremacy. In spite of the almost religious fervour with which he
speaks of it ("the most orthodox of his disciples" paraphrases his
meaning by describing its content as "the service and vision of God"),
it is clear that he identified it with the life of the philosopher, as
he understood it, a life of ceaseless intellectual activity in which at
least at times all the distractions and disturbances inseparable from
practical life seemed to disappear and become as nothing. This ideal was
partly an inheritance from the more ardent idealism of his master Plato,
but partly it was the expression of personal experience.
