But could he gain a knowledge of that agency, so as to be able to apply it in practice, we might then say that another canonical book of the word of God had been discovered.
If man could alter the properties of the lever, so also could he alter the properties of the triangle: for a lever (taking that sort of lever which is called a steel-yard, for the sake of explanation) forms, when in motion, a triangle.

The line it descends from, (one point of that line being in the fulcrum,) the line it descends to, and the chord of the arc, which the end of the lever describes in the air, are the three sides of a triangle.

The other arm of the lever describes also a triangle; and the corresponding sides of those two triangles, calculated scientifically, or measured geometrically,--and also the sines, tangents, and secants generated from the angles, and geometrically measured,--have the same proportions to each other as the different weights have that will balance each other on the lever, leaving the weight of the lever out of the case.
It may also be said, that man can make a wheel and axis; that he can put wheels of different magnitudes together, and produce a mill.

Still the case comes back to the same point, which is, that he did not make the principle that gives the wheels those powers.

This principle is as unalterable as in the former cases, or rather it is the same principle under a different appearance to the eye.
The power that two wheels of different magnitudes have upon each other is in the same proportion as if the semi-diameter of the two wheels were joined together and made into that kind of lever I have described, suspended at the part where the semi-diameters join; for the two wheels, scientifically considered, are no other than the two circles generated by the motion of the compound lever.
It is from the study of the true theology that all our knowledge of science is derived; and it is from that knowledge that all the arts have originated.
The Almighty lecturer, by displaying the principles of science in the structure of the universe, has invited man to study and to imitation.
