Matter and Substance A Tract Book Essay By Anthony J. Fejfar, B.A., J.D., Esq., Coif © Copyright 2007 by Anthony J. Fejfar When I was a kid growing up, in gradeschool we had a gradeschool science class where we were told that the Earth and the Universe were made of Matter. They really didn’t define Matter for us in class, but Wikipedia, the Online Encyclopedia defines Matter as “the substance of which material objects are composed.” Put another way, Matter is Material Substance. The reason I point this out is that some persons doubt the existence of Substance as a metaphysical quiddity. In fact, Substance is analogous to and closely related to the commonly held scientific concept of Matter. Matter is that of which all that is material is composed, while Substance is that of which all that is real is composed. The commonly held scientific belief in Matter proves the existence of Substance by analogy.
