Life is known to be a process of combustion; intellect is the light produced by this process.
The life of a fool is worse than death.
Since everything which exists or happens for a man exists only in his consciousness and happens for it alone, the most essential thing for a man is the constitution of this consciousness, which is in most cases far more important than the circumstances which go to form its contents.
Fundamentally it is only our own basic thoughts that possess truth and life, for only these do we really understand through and through. The thoughts of another that we have read are crumbs from another's table, the cast-off clothes of an unfamiliar guest.
Intellect is invisible to the man who has none.
To live alone is the fate of all great souls.
