Ernst Heinrich Philipp August Haeckel & Thomas Henry Huxley 
Freedom in Science and Teaching. from the German of Ernst Haeckel 

pub One.info present you this new edition. In complying with the wish of the publishers of Professor Haeckel’s[v] reply to Professor Virchow, that I should furnish a prefatory note expressing my own opinion in respect of the subject-matter of the controversy, Gay’s homely lines, prophetic of the fate of those "who in quarrels interpose, " emerge from some brain-cupboard in which they have been hidden since my childish days. In fact, the hard-hitting with which both the attack and the defence abound, makes me think with a shudder upon the probable sufferings of the unhappy man whose intervention should lead two such gladiators to turn their weapons from one another upon him. In my youth, I once attempted to stop a street fight, and I have never forgotten the brief but impressive lesson on the value of the policy of non-intervention which I then received.
