Variant: Character is like a tree and reputation like a shadow. The shadow is what we think of it; the tree is the real thing.

But of a shadow, summ'd with all his substance.”

“What is it that distinguishes man from animals? It is not his upright posture.”
"Affluence and Ennui in Our Society" in For the Love of Life (1986) translated by Robert and Rita Kimber
Context: What is it that distinguishes man from animals? It is not his upright posture. That was present in the apes long before the brain began to develop. Nor is it the use of tools. It is something altogether new, a previously unknown quality: self-awareness. Animals, too, have awareness. They are aware of objects; they know this is one thing and that another. But when the human being as such was born he had a new and different consciousness, a consciousness of himself; he knew that he existed and that he was something different, something apart from nature, apart from other people, too. He experienced himself. He was aware that he thought and felt. As far as we know, there is nothing analogous to this anywhere in the animal kingdom. That is the specific quality that makes human beings human.

“Creatures of a day! What is a man?
What is he not? A dream of a shadow
Is our mortal being.”
Pythian 8, line 95-8; pages 162-3. (446 BC)
Context: Creatures of a day! What is a man?
What is he not? A dream of a shadow
Is our mortal being. But when there comes to men
A gleam of splendour given of Heaven,
Then rests on them a light of glory
And blesséd are their days.

The Tragic Sense of Life (1913), VI : In the Depths of the Abyss
Context: In the most secret chamber of the spirit of him who believes himself convinced that death puts an end to his personal consciousness, his memory, for ever, and all unknown to him perhaps, there lurks a shadow, a vague shadow, a shadow of uncertainty, and while he says within himself, "Well, let us live this life that passes away, for there is no other!" the silence of this secret chamber speaks to him and murmurs, "Who knows!... " These voices are like the humming of a mosquito when the south-west wind roars through the trees in the wood; we cannot distinguish this faint humming, yet nevertheless, merged in the clamor of the storm, it reaches the ear.
