An echo is a good way to describe the photogram, which is a visual echo of the real object. That's why I like to work with the photogram, because the contact with what is represented is actual. It's as if the border between the world and the print is osmotic.
It seems to be the special peculiarity of human beings that they reflect: they think about thinking and know that they know. This, like other feedback systems, may lead to vicious circles and confusions if improperly managed, but self-awareness makes human experience resonant. It imparts that simultaneous "echo" to all that we think and feel as the box of a violin reverberates with the sound of the strings. It gives depth and volume to what would otherwise be shallow and flat.
I beseech Thee, my God, I would fain know, if so Thou willest, for what purpose my baptism was then deferred? was it for my good that the rein was laid loose, as it were, upon me, for me to sin? or was it not laid loose? If not, why does it still echo in our ears on all sides, "Let him alone, let him do as he will, for he is not yet baptised?" but as to bodily health, no one says, "Let him be worse wounded, for he is not yet healed." How much better then, had I been at once healed; and then, by my friends' diligence and my own, my soul's recovered health had been kept safe in Thy keeping who gavest it.
Deep into that darkness peering, long I stood there wondering, fearing, Doubting, dreaming dreams no mortals ever dared to dream before; But the silence was unbroken, and the stillness gave no token, And the only word there spoken was the whispered word, "Lenore?" This I whispered, and an echo murmured back the word, "Lenore!" — Merely this, and nothing more
Seated one day at the organ, I was weary and ill at ease, and my fingers wandered idly over the noisy keys. It seemed the harmonious echo from our discordant life.
I have not loved the World, nor the World me; I have not flattered its rank breath, nor bowed To its idolatries a patient knee, Nor coined my cheek to smiles,-nor cried aloud In worship of an echo.
There is a place where time stands still ...illuminated by only the most feeble red light, for light is diminished to almost nothing at the center of time, its vibrations slowed to echoes in vast canyons, its intensity reduced to the faint glow of fireflies.
A dissolute character is more dissolute in thought than in deed. And the same is true of violence. Our violence in word and deed is but a feeble echo of the surging violence of thought in us.
