Onward

Let us start with C. S. Lewis's comment on the future, from The Screwtape Letters [ch. 15]:

Our business is to get them away from the eternal, and from the Present. With this in view, we sometimes tempt a human (say a widow or a scholar) to live in the Past. But this is of limited value, for they have some real knowledge of the past and it has a determinate nature and, to that extent, resembles eternity. It is far better to make them live in the Future. Biological necessity makes all their passions point in that direction already, so that thought about the Future inflames hope and fear. Also, it is unknown to them, so that in making them think about it, we make them think of unrealities. In a word, the Future is, of all things, the thing least like eternity. It is the most completely temporal part of time—for the Past is frozen and no longer flows, and the Present is all lit up with eternal rays. . . . Hence nearly all vices are rooted in the future. Gratitude looks to the past and love to the present; fear, avarice, lust, and ambition look ahead. . . .

To be sure, the Enemy wants men to think of the Future too—just so much as is necessary for now planning the acts of justice or charity which will probably be their duty tomorrow. The duty of planning the morrow’s work is today’s duty; though its material is borrowed from the future, the duty, like all duties, is in the Present. . . .

But we want a man hag-ridden by the Future. . . . We want a whole race perpetually in pursuit of the rainbow’s end, never honest, nor kind, nor happy now, but always using as mere fuel wherewith to heap the altar of the future every real gift which is offered them in the Present.

With that in mind, consider this. Or this. Or this. Well done, Screwtape.
