The doctrine of Evolution as it is now becoming current in popular
literature is one-tenth bad Science and nine-tenths bad Philosophy.
Darwin was not strictly an Evolutionist, and rarely used the word.
He endeavored simply to show that Species were enlarged varieties.
The title of his epoch making book was, "The Origin of Species by
Natural Selection." On the larger questions of the origin of genera
and the more comprehensive orders of plants and animals, he spoke
with great caution and only referred to such theories as things
"dimly seen in the distance."
