From these premises there follows the inevitable conclusion that the chief end of man is progress in virtue, or, we might better say, in all the virtues, though virtue in reality is but one. Our progress in philosophy is the result of constant and uninterrupted effort. Parallel to this is our progress in virtue; if we relax our efforts for a moment we incur the danger of letting vice get a hold upon us. He who is always in conflict with vice, with his evil passions, may rest assured that he is making progress in virtue. But our love for virtue must partake of the nature of a passion; in it we ought to find our highest gratification, so that if we are interrupted in our pursuit we shall long to return to it. The aim and purpose of our philosophy must be practical, and it is chiefly in our activity as a citizen and a man in all the multiplex relations of life, that we may test our love for it. Yet, the true philosopher is not ostentatious, and it makes little difference to him whether the world recognizes him as such or not. He ought to seek internal satisfaction, not public acknowledgement. Herein Plutarch takes his stand in opposition to many of his countrymen who aspired to the name and title of philosophers, but did little to deserve them. How men of sense regarded them has been pointed out elsewhere. We may also measure our progress in philosophy, that is, in virtue, by our love of the beautiful and the good; by our attitude towards praise and blame. We ought neither to seek the one nor avoid the other. If we really desire to correct our faults and shortcomings, we will be ready at all times to listen to advice and to heed criticism; nor will we conceal any part of our nature or cover up any of our acts in order to seem what we are not. Nevertheless, when we are firmly convinced that we are in the right, it is our duty to go forward in the course we have marked out for ourselves, no matter what others may think or say.
