It would be the seminal accomplishment of humanity.
The body of the work, however, is fruitful in seminal ideas, though some statements may be rash and some conclusions extravagant.
Each testis communicates by means of an efferent duct with a common collecting duct of its side of the body, which opens on to the exterior by means of a protrusible penis, and to which is sometimes appended a seminal vesicle.
It is interesting to observe that here already two things are brought forward as proofs of the omnipotence and care of God: one is the creation of man out of a seminal drop - an idea to which Mahomet often recurs; the other is the then recently introduced art of writing, which the Prophet instinctively seizes on as a means of propagating his doctrines.
There is at the same time the special doctrine of the Aoyos o'7rep,uartn6s, the seminal Logos, or the law of generation in the world, the principle of the active reason working in dead matter.
