and equally liable, on the other hand, to the danger of overlooking the wide gulf which separates Religion from Irreligion, and Theism from Atheism. There is much room for the exercise both of Christian candor and of critical discrimination, in forming our estimate of the characters of men from the opinions which they hold, when these opinions relate not to the vital truths of religion, but to collateral topics, more or less directly connected with them. It is eminently necessary, in treating this subject, to discriminate aright between systems which are essentially and avowedly atheistic, and those particular opinions on cognate topics which have sometimes been applied in support of Atheism, but which may, nevertheless, be held by some _salva fide_, and without conscious, still less avowed, Infidelity. And hence Buddaeus and other divines have carefully distinguished between the radical principles or grounds of Atheism, and those opinions which are often, but not invariably, associated with it.[4] But it is equally or still more dangerous, on the other hand, to admit a mere nominal recognition of God as a sufficient disproof of Atheism, without inquiring what conception is entertained of His nature and perfections; whether He be conceived of as different from, or identical with, Nature; as a living, personal, and intelligent Being, distinct from the universe, or as the mere sum of existing things; as a free Creator and Moral Governor, or as a blind Destiny and inexorable Fate. These are vital questions, and they cannot be evaded without serious detriment to the cause of religion. A few examples will suffice to prove our assertion. M. Cousin contends that _Atheism is impossible_, and assigns no other reason for his conviction than this,--that the existence of God is necessarily implied in every affirmation, and may be logically deduced from the premises on which that affirmation depends.[5] His reasoning may possibly be quite conclusive _in point of logic_, in so far as it is an attempt to show that the existence of God _ought_ to be deduced from the consciousness of thought; but it cannot be held conclusive as to _the matter of fact_, that there is no Atheism in the world, unless it can be further shown that all men know and acknowledge His existence as a truth involved in, and deducible from, their conscious experience. Yet he does not hesitate to affirm that "every thought implies a spontaneous faith in God;" nay, he advances further, and adds that even when the sage "denies the existence of God, still his words imply the idea of God, and that belief in God remains unconsciously at the bottom of his heart." Surely the denial or the doubt of God's existence amounts to Atheism, however inconsistent that Atheism may be with the natural laws of thought, or the legitimate exercise of speech.
