Note 6 — Chapter II · GEOGRAPHICAL DISTRIBUTION OF SLAVERY.

We shall find that several savage tribes have to a considerable extent been influenced by civilized or semi-civilized nations. In such cases the question arises: have we to deal here with phenomena of unadulterated savage life? This question is important and deserves full attention. We shall see that many savage tribes in their true aboriginal state have been acquainted with slavery, whereas many others when first discovered did not practise it; so neither the existence nor the non-existence of slavery must necessarily be due to foreign interference; either may be aboriginal, and must be supposed to be so wherever there is not a strong presumption to the contrary6. But there are also many cases in which foreign influence has undoubtedly been at work. We must, then, make a distinction. If the influence of the civilized or semi-civilized nation has led to a, so to speak, normal development, i.e. a development, which lies within the limits of primitive culture, we have to deal with a phenomenon of savage life. For instance, commercial intercourse with a nation of higher civilization has brought about an accumulation of wealth and a social differentiation, which render the existence of slavery possible. In such case we may safely speak of slavery as practised by savages, for it is the effect of trade in general, not of intercourse with a civilized nation as such, that we have to deal with here. If, on the contrary, there has been an abnormal development, i.e. a development which does not take place in countries inhabited by savages only, the present condition of the savage tribe has no interest to us. For instance, measures have been taken by a civilized nation on purpose to abolish slavery. Then we, for our purpose, must consider the savage tribe concerned as keeping slaves, and pay attention only to the descriptions of its institutions as they were before the abolition.
