Abstract
We shall endeavour to lay more securely the foundation of our future structure, in a brief attempt to ascertain our ideas and give precise definitions of our terms. The terms enumerated above are sufficiently precise, and convey very clear and distinct ideas. These terms are cause, effect and law of nature.
