4. First, then, _happiness is not the practice of the moral virtues of temperance and fortitude_. Temperance makes a man strong against the temptations to irrationality and swinishness that come of the bodily appetites. But happiness lies, not in deliverance from what would degrade man to the level of the brutes, but in something which shall raise man to the highest level of human nature. Fortitude, again, is not exercised except in the hour of danger; but happiness lies in an environment of security, not of danger. And in general, the moral virtues can be exercised only upon occasions, as they come and go; but happiness is the light of the soul, that must burn with steady flame and uninterrupted act, and not be dependent on chance occurrences. 5. Secondly, _happiness is not the use of the practical understanding with a view to production_. Happiness is an end in itself, a terminus beyond which the act of the will can go no further; but this use of the understanding is in view of an ulterior end, the thing to be produced. That product is either useful or artistic; if useful, it ministers to some further end still; if artistic, it ministers to contemplation. Happiness, indeed, is no exercise of the practical understanding whatever. The noblest exercises of practical understanding are for military purposes and for statesmanship. But war surely is not an end in itself to any right-minded man. Statecraft, too, has an end before it, the happiness of the people. It is a labour in view of happiness. We must follow down the third lane, and say: 6. _Happiness is the act of the speculative understanding contemplating for contemplation's sake_. This act has all the marks of happiness. It is the highest act of man's highest power. It is the most capable of continuance. It is fraught with pleasure, purest and highest in quality. It is of all acts the most self-sufficient and independent of environment, provided the object be to the mind's eye visible. It is welcome for its own sake, not as leading to any further good. It is a life of ease and leisure: man is busy that he may come to ease. 7. Aristotle says of this life of continued active contemplation:
