“The probability of life originating from accident is comparable to the probability of the unabridged dictionary resulting from an explosion in a printing shop.”
“The question is this -- Is man an ape or an angel? My Lord, I am on the side of the angels. I repudiate with indignation and abhorrence these new fanged theories.”
“The historic ascent of humanity, taken as a whole, may be summarized as a succession of victories of consciousness over blind forces -- in nature, in society, in man himself.”
“The pre-human creature from which man evolved was unlike any other living thing in its malicious viciousness toward its own kind. Humanization was not a leap forward but a groping toward survival.”
“Man has lost the basic skill of the ape, the ability to scratch its back. Which gave it extraordinary independence, and the liberty to associate for reasons other than the need for mutual back-scratching.”
“The more specific idea of Evolution now reached is -- a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.”
“It is disturbing to discover in oneself these curious revelations of the validity of the Darwinian theory. If it is true that we have sprung from the ape, there are occasions when my own spring appears not to have been very far.”
“Organic life, we are told, has developed gradually from the protozoon to the philosopher, and this development, we are assured, is indubitably an advance. Unfortunately it is the philosopher, not the protozoon, who gives us this assurance.”
“It is curious how there seems to be an instinctive disgust in Man for his nearest ancestors and relations. If only Darwin could conscientiously have traced man back to the Elephant or the Lion or the Antelope, how much ridicule and prejudice would have been spared to the doctrine of Evolution.”
“We live between two worlds; we soar in the atmosphere; we creep upon the soil; we have the aspirations of creators and the propensities of quadrupeds. There can be but one explanation of this fact. We are passing from the animal into a higher form, and the drama of this planet is in its second act.”
“Evolution is the law of policies: Darwin said it, Socrates endorsed it, Cuvier proved it and established it for all time in his paper on ''The Survival of the Fittest.'' These are illustrious names, this is a mighty doctrine: nothing can ever remove it from its firm base, nothing dissolve it, but evolution.”
“Evolution is gaining the psychic zones of the world... life, being and ascent of consciousness, could not continue to advance indefinitely along its line without transforming itself in depth. The being who is the object of his own reflection, in consequence, of that very doubling back upon himself becomes in a flash able to raise himself to a new sphere.”
“An extra-terrestrial philosopher, who had watched a single youth up to the age of twenty-one and had never come across any other human being, might conclude that it is the nature of human beings to grow continually taller and wiser in an indefinite progress towards perfection; and this generalization would be just as well founded as the generalization which evolutionists base upon the previous history of this planet.”
