After meditating deeply on this topic, it occurred to me that light, upon passing from one medium to another, has to make a choice, whether to follow the path of shortest distance (the straight line) or the path of least time. But why should it prefer time over space? Light cannot travel both paths at once, yet how does it decide to take one path over another? Rather than taking either of these paths per se, light takes the path that offers a real advantage: light takes the path that minimizes its action.

The empire of Saturnus is gone by;
Lord of the secret birth of things is he;
Within the lap of earth, and in the depths
Of the imagination dominates;
And his are all things that eschew the light.
The time is o'er of brooding and contrivance,
For Jupiter, the lustrous, lordeth now,
And the dark work, complete of preparation,
He draws by force into the realm of light.
Now must we hasten on to action, ere
The scheme, and most auspicious positure
Parts o'er my head, and takes once more its flight,
For the heavens journey still, and adjourn not.
Friedrich Schiller
My philosophy of life is that the meek shall inherit nothing but debasement, frustration and ignoble deaths; that there is security in personal strength; that you can fight City Hall and win; that any action is better than no action, even if it's the wrong action; that you never reach glory or self-fulfillment unless you're willing to risk everything, dare anything, put yourself dead on the line every time; and that once one becomes strong or rich or potent or powerful it is the responsibility of the strong to help the weak become strong.
Harlan Ellison
Poetry operates by raising our curiosity, engaging the mind by degrees to take an interest in the event, keeping that event suspended, and surprising at last with an unexpected catastrophe. The painter's art is more confined, and has nothing that corresponds with, or perhaps is equivalent to, this power and advantage of leading the mind on, till attention is totally engaged. What is done by Painting, must be done at one blow; curiosity has received at once all the satisfaction it can ever have.
Joshua Reynolds
Yet I am not more sure that my soul lives, than I am that perverseness is one of the primitive impulses of the human heart - one of the indivisible primary faculties, or sentiments, which give direction to the character of man. Who has not, a hundred times, found himself committing a vile or a stupid action, for no other reason than because he knows he should not? Have we not a perpetual inclination, in the teeth of our best judgement, to violate that which is Law, merely because we understand it to be such?
Edgar Allan Poe
Never trample on any soul though it may be lying in the veriest mire; for that last spark of self-respect is its only hope, its only chance; the last seed of a new and better life: - the voice of God that whispers to it: "You are not what you ought to be, and you are not what you can be. You are still God's child, still an immortal soul. You may rise yet. and fight a good fight yet, and be a man once more, after the likeness of God who made you, and Christ who died for you!"
Charles Kingsley
