This must not be suited to the one only, nor to the few but to the many and, indeed at best, to all mankind. Another man called Aristotle left us two main basics. One was that Good leads Happiness. The other was that man should not try to rush to excess but recognise the moderate or the Mean as Aristotle's word becomes in translation. The word happiness is one such.
Love is another.
In some ways these two words appear selfish and stupid and in other ways of the greatest wisdom. More thought must be given to words we use as to their precise meanings in context. We should not be taken in by grandiose words which often put us off study. It is true that some great and genuine philosophers use words of their own creation to cover the whole area of their hard thinking. So metaphysics suggests that which we cannot understand or that which is beyond our present grasp but which intrigues us towards exploration.
