For my part, I would say that the male sperm and seeds of plants have been penetrated so far that there is nothing further to discover in this great secret, but I could err in my opinion.

Man comes not from an egg but from an animalcule that is found in male sperm.

For my part, I hold it equally impossible for a small shellfish to be produced without generation as for a whale to have its origin from the mud.

How little do we discover in comparison of those things which now are and forever will be hidden from our sight? The whole of which I am fully persuaded no one will ever be able to dive into, and to explain their causes and effects.

I have oft-times been besought, by divers gentlemen, to set down on paper what I have beheld through my newly invented microscopia, but I have generally declined.

In my opinion, faith helps in many contexts.
