Read it through once

The relations of these remain unchanged; and such is the material of our knowledge. What is the cause of life? that is, how was it produced, or what agencies distinct from life have acted or act upon life? All recorded generations of mankind have weariedly busied themselves in inventing answers to this question; and the result has been,--Religion. Yet, that the basis of all things cannot be, as the popular philosophy alleges, mind, is sufficiently evident. Mind, as far as we have any experience of its properties, and beyond that experience how vain is argument! cannot create, it can only perceive. It is said also to be the cause. But cause is only a word expressing a certain state of the human mind with regard to the manner in which two thoughts are apprehended to be related to each other. If any one desires to know how unsatisfactorily the popular philosophy employs itself upon this great question, they need only impartially reflect upon the manner in which thoughts develop themselves in their minds. It is infinitely improbable that the cause of mind, that is, of existence, is similar to mind.
