On what authority, then, do you venture to attack universal consent, and give the lie to the human race?
Who are you, that you should question the judgment of the nations and the ages?
Of what consequence to you, reader, is my obscure individuality?
I live, like you, in a century in which reason submits only to fact and to evidence.

My name, like yours, is TRUTH-SEEKER.

[6] My mission is written in these words of the law: SPEAK WITHOUT HATRED AND WITHOUT FEAR; TELL THAT WHICH THOU KNOWEST! The work of our race is to build the temple of science, and this science includes man and Nature.

Now, truth reveals itself to all; to-day to Newton and Pascal, tomorrow to the herdsman in the valley and the journeyman in the shop.

Each one contributes his stone to the edifice; and, his task accomplished, disappears.
