LECTURE I.

CAUSES OF SCEPTICISM.

1 TIMOTHY, III. 7.

EVER LEARNING, AND NEVER ABLE TO COME TO THE KNOWLEDGE OF THE TRUTH.

TRUTH is the reality of things-It is natural as it respects the material world, and moral as it respects mind, accountability, and moral government. Our knowledge of truth is by consciousness, intuition, the senses, and evidence. Consciousness is the

mind's recognition of its own being, powers, and actions. Intuition is the mind's perception of obvious, primary truths, which are the elements of demonstration-such as, that every effect must have a cause; and that the parts are equal to the whole. It is intuition which constitutes the premises of demonstration, the primary truths being seen by the mind, and each step in the process, also, being a matter of intuition, or of mental perception. The reports of the senses are called knowledge, because they so uniformly correspond with the reality of

things, that occasional aberration occasions no distrust, but rather confirms the general rule. There is a yet wider field of knowledge which lies without the sphere of consciousness, and beyond the range of intuition, and the cognizance of the senses, the realities of which are certified to us by evidence; and the confidence produced is called belief. The evidence which sustains belief, is either the evidence of human testimony, or the accumulation of probabilities from the uniform operation of the laws of nature. This last evidence rests on the self-evident proposition, that no effect can exist without a cause— that what has been and is, will continue to be, where there is no perceived cause of change, derived from a supposition of a stated order of cause and effect; and rises from faint probability to moral certainty, according to the frequency and uniformity of the effects produced. Had the sun never risen before to-day, the evidence of its rising to-morrow, would be no greater than the appearance of a meteor in the sky would be of its return. But had the meteor appeared as uniformly as the sun has appeared, the evidence in both cases would be equal, of a stated order of cause and effect.

The difference between demonstration and moral certainty, is, that in one case the mind sees the object of comparison, and sees the result, which, of course, is knowledge; but in the other, derives *ts confidence from the perception of probabilities multiplied till they produce confidence, or moral certainty. On the whole, consciousness, intuition, the senses, the evidence of testimony, and analogy,
