CASTES IN INDIA
83
To start with M. Senart. He draws attention to the "idea of pollution" as a characteristic of Caste. With regard to this point it may be safely said that it is by no means a peculiarity of Caste as such. It usually originates in priestly ceremonialism and is a particular case of the general belief in purity. Consequently its necessary connection with Caste may be completely denied without damaging the working of Caste. The "idea of pollution" has been attached to the institution of Caste, only because the Caste that enjoys the highest rank is the priestly Caste: while we know that priest and purity are old associates. We may therefore conclude that the "idea of pollution" is a characteristic of Caste only in so far as Caste has a religious flavour. Mr. Nesfield in his way dwells on the absence of messing with those outside the Caste as one of its characteristics. In spite of the newness of the point we must say that Mr. Nesfield has mistaken the effect for the cause. Caste, being a self-enclosed unit naturally limits social intercourse, including messing etc., to members within it. Consequently this absence of messing with outsiders is not due to positive prohibition, but is a natural result of Caste, i. e., exclusiveness. No doubt this absence of messing, originally due to exclusiveness, acquired the prohibitory character of a religious injunction, but it may be regarded as a later growth. Sir H. Risley, makes no new point deserving of special attention.
We now pass on to the definition of Dr. Ketkar, who has done much for the elucidation of the subject. Not only is he a native, but he has also brought a critical acumen and an open mind to bear on his study of Caste. His definition merits consideration, for he has defined Caste in its relation to a system of Castes, and has concentrated his attention only on those characteristics which are absolutely necessary for the existence of a Caste within a system, rightly excluding all others as being secondary or derivative in character. With respect to his definition it must, however, be said that in it there is a slight confusion of thought, lucid and clear as otherwise it is. He speaks of Prohibition of Intermarriage and Membership by Autogeny as the two characteristics of Caste. I submit that these are but two aspects of one and the same thing, and not two different things as Dr. Ketkar supposes them to be. If you prohibit inter-marriage the result is that you limit membership to those born within the group. Thus the two are the obverse and the reverse sides of the same medal.
This critical evaluation of the various characteristics of Caste leaves no doubt that prohibition, or rather the absence of intermarriage-endogamy, to be concise—is the only one that can be called the essence of Caste when rightly understood. But some may deny this on abstract anthropological grounds, for there exist endogamous groups without giving rise to the problem of Caste. In a general way this may be true, as endogamous societies, culturally different, making their abode in localities more or less removed, and having little to do with each other, are a physical reality. The negroes and the whites and the various tribal groups that go by the name of American Indians in the United States may be cited as more or less appropriate illustrations in support of this view. But we must not confuse matters, for in India the situation is different. As pointed out before, the peoples of India form a homogeneous whole. The various races of India occupying definite territories have more or less fused into one another and do possess a cultural unity, which is the only criterion of a homogeneous population. Given this homogeneity as a basis, Caste becomes a problem altogether new in character and wholly absent in the situation constituted by the mere propinquity of endogamous social or tribal
