A blind god could not make a seeing man.

Let us look for a little at a few of the many marks of design in this organ to which God thus refers us.
We shall first observe the mechanical skill displayed in the formation of the eye, and then the optical arrangements, or rather a few of them, for there are more than eight hundred distinct contrivances already observed by anatomists in the dead eye, while the great contrivance of all, the power of seeing, is utterly beyond their ken.

I hold in my hand a box made of several pieces of wood glued together, and covered on the outside with leather.

Inside it is lined with cotton, and the cotton has a lining of fine white silk.

You at once observe that it is intended to protect some delicate and precious article of jewelry, and that the maker of this box must have been acquainted with the strength of wood, the toughness of leather, the adhesiveness of glue, the softness and elasticity of cotton, the tenacity of silk, and the mode of spinning and weaving it, the form of the jewel to be placed in it, and the danger against which this box would protect it--ten entirely distinct branches of knowledge, which every child who should pick up such a box in the street would unhesitatingly ascribe to its maker.
