I have never felt any inward assurance of genius, or any presentiment of glory or of happiness. I have never seen myself in imagination great or famous, or even a husband, a father, an influential citizen.

What dreams I have are all vague and indefinite; I ought not to live, for I am now scarcely capable of living.

Knowledge, love, power-there is the complete life.
