Note 1 — Chapter VI · How Is Organic Matter Produced?
Joens Elias Fries translation
The latest researches in regard to the newly discovered corpuscles show that these “bodies” have a mass proportional to the square of their velocity, thus forcing us to conclude that they at rest have no mass. Perhaps, therefore, the ancient dualistic world of matter and force is merging into a larger unity where life directs force to serve its specific purposes.—Translator’s note.
