She alone had been blind to his merit. Why? Because he loved her and she did not love him. What was it in the human heart that made you despise a man… - William Somerset Maugham

What was it in the human heart that made you despise a man because he loved you?

Self-doubt, which is the artist's bitterest enemy.

From a social standpoint the man of science does not exist.

Each one of us is alone in the world. He is shut in a tower of brass, and can communicate with his fellows only by signs, and the signs have no common value, so that their sense is vague and uncertain. We seek pitifully to convey to others the treasures of our heart, but they have not the power to accept them, and so we go lonely, side by side but not together, unable to know our fellows and unknown by them. We are like people living in a country whose language they know so little that, with all manner of beautiful and profound things to say, they are condemned to the banalities of the conversation manual. Their brain is seething with ideas, and they can only tell you that the umbrella of the gardener's aunt is in the house.
