To the principles which have now been stated, we are also to refer a point in the philosophy of human nature which presents a subject of most interesting reflection. I allude to the fact, that the great truths of religious belief are so often rejected, by men who have acquired a reputation for exalted powers of understanding in other departments of intellectual inquiry. The fact is one of intense interest; and we can scarcely wonder that superficial observers should have deduced from it an impression, that it implies something defective in the evidence by which these truths are proposed to our reception. But the conclusion is entirely unwarranted, and the important principle cannot be too often repeated, that the attainment of truth in moral inquiries is essentially connected with the moral condition of the inquirer. On this depends the anxious care with which he has directed his mind to the high pursuit, under a deep and solemn feeling of its supreme importance. On this depends the sincere and humble and candid love of truth with which he has conducted it, apart alike from prejudice and frivolity. For without these essential elements of character, the most exalted intellect may fail of reaching the truth,--the most acute understanding may only wander into delusion and falsehood. * * * * * Before concluding this subject, there is another point which deserves to be alluded to;--namely, the influence produced upon all our moral judgments and decisions by Attention. This important process of the mind we have had occasion to mention in various parts of our inquiry. It consists, as we have seen, in directing the thoughts, calmly and deliberately, to all the facts and considerations by which we ought to be influenced in the particular case which is under our view; and it should be accompanied by an anxious and sincere desire to be guided, both in our opinions and conduct, by the true and relative tendency of each of them. It is a voluntary process of the mind which every man has the power to perform; and on the degree in which it is habitually exercised, depend some of the great differences between one man and another in their moral condition. We have repeatedly had occasion to mention that morbid state of the mind, in which moral causes seem to have lost their proper influence, both on the volitions of the will, and even on the conclusions of the judgment:--But it is a truth which cannot be too often referred to, how much this condition is influenced by the mental process which we are now considering. It originates, indeed, in some degree of that distortion of moral feeling, in consequence of which the inclinations wander from the strict path of rectitude;--but the primary effect of this loss of mental harmony, and that by which it is perpetuated, appears to be chiefly a habitual misdirection of the attention,--or a total want of consideration of the truths and motives,
