Hope is one of the Theological virtues. This means that a continual looking forward to the eternal world is not (as some modern people think) a form of escapism or wishful thinking, but one of the things a Christian is meant to do. It does not mean that we are to leave the present world as it is. If you read history you will find that the Christians who did most for the present world were just those who thought most of the next.
C. S. LewisThere is something which unites magic and applied science (technology) while separating them from the "wisdom" of earlier ages. For the wise men of old, the cardinal problem of human life was how to conform the soul to objective reality, and the solution was wisdom, self-discipline , and virtue. For the modern, the cardinal problem is how to conform reality to the wishes of man, and the solution is a technique.
