Velazquez found the perfect balance between the ideal illustration which he was required to produce, and the overwhelming emotion he aroused in the spectator.
We maintain, and have said in the Ethics, if the arguments there adduced are of any value, that happiness is the realization and perfect exercise of virtue, and this not conditional, but absolute. And I used the term 'conditional' to express that which is indispensable, and 'absolute' to express that which is good in itself.
If a thing happens once, it can happen again. If any human being has ever realised perfection, we too can do so. If we cannot become perfect here and now, we never can in any state or heaven or condition we may imagine.
