My attention was fixed upon every object the most insupportable to the delicacy of the human feelings.

I saw how the fine form of man was degraded and wasted; I beheld the corruption of death succeed to the blooming cheek of life; I saw how the worm inherited the wonders of the eye and brain.

I paused, examining and analysing all the minutiae of causation, as exemplified in the change from life to death, and death to life, until from the midst of this darkness a sudden light broke in upon me--a light so brilliant and wondrous, yet so simple, that while I became dizzy with the immensity of the prospect which it illustrated, I was surprised that among so many men of genius who had directed their inquiries towards the same science, that I alone should be reserved to discover so astonishing a secret.
Remember, I am not recording the vision of a madman.

The sun does not more certainly shine in the heavens than that which I now affirm is true.

Some miracle might have produced it, yet the stages of the discovery were distinct and probable.
