But to waive all objections drawn from this topic, I affirm, that there are other parts of the universe (besides the machines of human invention) which bear still a greater resemblance to the fabric of the world, and which, therefore, afford a better conjecture concerning the universal origin of this system.

These parts are animals and vegetables.
The world plainly resembles more an animal or a vegetable, than it does a watch or a knitting-loom.

Its cause, therefore, it is more probable, resembles the cause of the former.

The cause of the former is generation or vegetation.

The cause, therefore, of the world, we may infer to be something similar or analogous to generation or vegetation.
But how is it conceivable, said DEMEA, that the world can arise from any thing similar to vegetation or generation?
Very easily, replied PHILO.
