That which, in all such cases, man calls the effect, is no other than the principle itself rendered perceptible to the senses.
Since, then, man cannot make principles, from whence did he gain a knowledge of them, so as to be able to apply them, not only to things on earth, but to ascertain the motion of bodies so immensely distant from him as all the heavenly bodies are?
From whence, I ask, could he gain that knowledge, but from the study of the true theology?
It is the structure of the universe that has taught this knowledge to man.

That structure is an ever-existing exhibition of every principle upon which every part of mathematical science is founded.

The offspring of this science is mechanics; for mechanics is no other than the principles of science applied practically.

The man who proportions the several parts of a mill uses the same scientific principles as if he had the power of constructing an universe, but as he cannot give to matter that invisible agency by which all the component parts of the immense machine of the universe have influence upon each other, and act in motional unison together, without any apparent contact, and to which man has given the name of attraction, gravitation, and repulsion, he supplies the place of that agency by the humble imitation of teeth and cogs.

All the parts of man's microcosm must visibly touch.
