It is probable that what we call thought is not an actual being, but no more than the relation between certain parts of that infinitely varied mass, … - Percy Bysshe Shelley

Swiftly walk over the western wave, Spirit of Night! Out of the misty eastern cave Where, all the long and lone daylight, Thou wovest dreams of joy and fear, Which make thee terrible and dear, — Swift be thy flight!

"Ozymandias"

I met a traveller from an antique land
Who said: "Two vast and trunkless legs of stone
Stand in the desert. Near them on the sand,
Half sunk, a shattered visage lies, whose frown
And wrinkled lip and sneer of cold command
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed.
And on the pedestal these words appear:
'My name is Ozymandias, King of Kings:
Look on my works, ye mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare,
The lone and level sands stretch far away."

Fear not for the future, weep not for the past
