But much is still wanting, before the followers of an evolution theory dare to use ethnology directly as a primitive history of the development of mankind, prepared and preserved for them. Especially the before-mentioned objection of the Duke of Argyll--that the lowest savages of our time can just as well be depraved as be men who remained stationary in the process of development--has here increased weight. Moreover, even with the savages of to-day, a rude state of their tools and a low condition of their mental and moral life are not so nearly parallel as to allow unrestricted conclusions to be drawn. Finally, we still know too little about the state of culture of the savages; and the deeper and higher the intellectual and ethical possessions of mankind are, the presence of which among the savages is in question, the more uncertain is our knowledge. This is especially true of the most important question in this connection--the question as to the existence {93} or absence of an idea of God, and the different stages of development of religious ideas. While some assume as an established fact, that there are savage tribes without any idea of God or any religion, and even give the names of these tribes, especially of some from the interior of South America; while Sir John Lubbock systematically enumerates seven stages of religious development, from atheism to the connection of religious with moral conceptions, and lets each single race run through these stages in an identical series until it either remains on one of the seven stages or arrives at the highest: yet, on the contrary, other equally trustworthy scientists assert that there is not a single human race without some idea of religion and of a God--indeed, not a single race without a monotheistic presentiment--and that all heathenism, down to its most degenerate stages, consists not so much in a non-recognition of a God as in ignoring him. They call especial attention to the difficulty of getting acquainted with the ideas of a savage tribe without living with it through many years and being intimate with its language and customs, and especially without enjoying the unrestricted confidence of the tribe. Mutual misunderstandings, a suspicious reserve, evasive and untrue answers to questions, are entirely unavoidable without those conditions. At any rate, the fact deserves attention, that those who have been longest and most active among savages, and who enjoyed their confidence to the fullest extent, all reached this result: they found them not only not without religion, but also not without a presentiment of the monotheistic idea of God. Livingstone, for instance, expressed this idea decidedly of all the African tribes {94} with which he became acquainted; and Jellinghaus gives the same evidence in regard to the Kols in South Asia.
