Is evolution partly true or a half-truth?

Now allow me in a few words to tell you what I did discover—matter, spirit and soul- germs. 

My speck of protoplasm or matter could not of itself take on any form whatever except simply that of rotundity—no, not even that, not even the lowest possible form without the soul-germ—

Soul-germs were distinct entities and never evolved one into another—or one from another—

No, not even the smallest or most minute—eternity was filled with these soul-germs, as it was also filled with matter and spirit. In fact, eternity consisted of three primary principles—matter, spirit, soul.

At first, they were all minute points or atoms—a minute point of pure flame or spirit, a minute point of matter or clothing, a minute point of soul or germ, but the soul-germ was that which fashioned and made use of—or covered itself with spirit and matter—

All soul-germs or germs of life, no matter how low in the scale they might be, were distinct entities and could not develop into aught but their own distinct individualities. It now seems very strange to me that I could have overlooked such a great eternal truth. 

How then is evolution partly true—or a half-truth?

Because one form of life makes the conditions for a higher form to appear—makes it possible for the next grade of soul-germs to take up the matter, which the former threw down after developing in full all that Nature designed them to be.

One may cross roses and flowers, but the tendency is ever to return to that from which they sprung.

I admit that climate and conditions favour certain species to the exclusion of others, but the germs are forever true to themselves and naturally gravitate or are attracted to the country or climate favorable to their growth.

I can never under any circumstances be other than Charles Darwin throughout eternity, and I am simply a developed soul-germ—the soul-germ of Charles Darwin developed up to my present condition.

I shall never evolute into any but Charles Darwin—no more will the slightest thing that lives, moves or has being and life. 

Dogs have been dogs from remote antiquity and they have never evolved into any other than dogs—horses will never evolute into any other than horses.

But you ask me—did man evolute from the ape or gorilla? and I reply—the ape and gorilla made it possible for the soul germs of mankind to at length be inhaled and developed as men upon earth—but all nations did not have the same root and the soul-germ of no man ever came from a monkey, ape or baboon. 

The highest possible ape or baboon was able to inhale and make use of a germ a shade higher than itself. In this sense evolution is true and as you see is but half-a-truth. The whole truth is involution and evolution.
