The plain rule is to do nothing in the dark, to be a party to nothing underhanded or mysterious, and never to put his foot where he cannot see the ground.
There are five dark matters and five lamps. Love of this world is darkness, and the fear of Allaah is its lamp. Sin is darkness, and its lamp is repentance. The grave is darkness, and its lamp is 'none has the right to be worshipped but Allaah, and Muhammad is the messenger of Allaah.' The hereafter is darkness, and its lamp is the good deed. The Siraat is darkness, and its lamp is certainty of faith.
Until the 1990s, there were few reliable observations about movement at the scale of the entire universe, which is the only scale dark energy effects. So dark energy could not be seen until we could measure things very, very far away.
I have seen the dark universe yawning Where the black planets roll without aim, Where they roll in their horror unheeded, Without knowledge, or lustre, or name.
Smile O voluptuous coolbreathed earth!
Earth of the slumbering and liquid trees!
Earth of departed sunset! Earth of the mountains misty-topt!
Earth of the vitreous pour of the full moon just tinged with blue!
Earth of shine and dark mottling the tide of the river!
Earth of the limpid gray of clouds brighter and clearer for my sake!
Far-swooping elbowed earth! Rich apple-blossomed earth!
Smile, for your lover comes!
Fie, thou dishonest Satan! I call thee by the most modest terms; for I am one of those gentle ones that will use the devil himself with courtesy: sayest thou that house is dark?
However much I may be impressed by the difference between a star and the dark space around it, I must not forget that I can see the two only in relation to each other, and that this relation is inseparable.
Forget not, never forget that you have promised me to use this silver to become an honest man.... Jean Valjean, my brother: you belong no longer to evil, but to good. It is your soul that I am buying for you. I withdraw it from dark thoughts and from the spirit of perdition, and I give it to God!
Beauty is a form of Genius--is higher, indeed, than Genius, as it needs no explanation. It is one of the great facts of the world, like sunlight, or springtime, or the reflection in the dark waters of that silver shell we call the moon. It cannot be questioned. It has divine right of sovereignty. It makes princes of those who have it.
Some men's wit is like a dark lantern, which serves their own turn and guides them their own way, but is never known (according to the Scripture phrase) either to shine forth before men, or to glorify their Father in heaven.
Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
