For Pantheism, whatever form it may assume, and whatever language it may adopt, can be regarded in no other light than as a system of Atheism, by all who have any definite conception of what is meant when we either affirm or deny the existence and government of a living, intelligent, personal God. As Atheism has appeared in several distinct forms, it is necessary to consider both its _generic nature_ and its _specific varieties_. It may be defined, generally, as that state of mind which involves either _the denial_ or _the doubt_ of the existence and government of God as an all-perfect Being, distinct from the created universe; or which leads to the habitual forgetfulness and wilful neglect of His claims as our Creator, Preserver, and Lord. This state of mind, whether evinced by words or by actions, contains in it the essence of Atheism, and it is recognized in Scripture, in each of its two aspects, as an evil alike natural and prevalent. The words of the Psalmist, "The fool hath said in his heart, No God,"[10] whether they be interpreted as the expression of an _opinion_ or of a _wish_, indicate in either case the existence of that state of mind which has just been described, and which may issue either in practical or speculative Atheism, according to the temperament of individual minds, and the influences which are brought to bear upon them. The same inspired writer has said,[11] that "The wicked through the pride of his countenance will not seek after God; God is not in all his thoughts;"--"He hath said in his heart, God hath forgotten; He hideth his face; He will never see it."--"Wherefore doth the wicked contemn God? he hath said in his heart, Thou wilt not require it;" And these words exhibit a graphic delineation, of that state of mind in which occasional thoughts of God are neutralized by habitual unbelief, and the warnings of conscience silenced by the denial of a supreme moral government. In like manner, when the apostle tells the Ephesian converts that at one time "they were _without God_ in the world,"[12] and the Galatians, that "when they knew not God, they did service unto them which by nature are no gods;" when he further speaks of some as "lovers of pleasures more than lovers of God," as "having a form of godliness, but denying the power thereof," as "professing that they know God, but _in works denying Him_;"[13]--in all these statements we see the generic nature of that ungodliness which cleaves as an inveterate disease to our fallen nature, and which, whether it appears only in the form of practical unbelief and habitual forgetfulness, or assumes the more daring aspect of avowed infidelity, contains in it the essence of Atheism.
