It is the true office of history to represent the events themselves, together with the counsels, and to leave the observations and conclusions thereupon to the liberty and faculty of every man's judgment
The man of the future who will redeem us not only from the hitherto reigning ideal but also from that which was bound to grow out of it, the great nausea, the will to nothingness, nihilism; this bell stroke of noon and of the great decision that liberates the will again and restores its goal to the earth and his hope to man; this Antichrist and anti-nihilist; this victor over God and nothingness - he must come one day.
Being well satisfied that, for a man who thinks himself to be somebody, there is nothing more disgraceful than to hold himself up as honored, not on his own account, but for the sake of his forefathers. Yet hereditary honors are a noble and splendid treasure to descendants.

If you killed the mosquito would it be missed? Verily, What is Man, that he should be considered of God?
