The other point that was made was that because education is of national importance, therefore it should be transferred to the Centre. If this argument is to be taken to its logical sequence, then practically every sphere of activity at present entrusted to the provinces would have to be transferred to the Centre. Medicine is of national importance, hygiene is of national importance, and practically all social services which are at present in the domain of the provinces will have to be transferred to the Centre. Now I think this is not the test for fixing the functions of the Centre and the provinces. To me it appears that the best should be that the subject besides being a subject of national importance, it should satisfy either of the three things which I shall just mention. Firstly, it should have a direct and immediate bearing on defence. Secondly, it should be of such a nature that it can best be managed only by the Centre. For instance, geological survey of the whole country can be best undertaken only by the Centre. Thirdly, it should be of such a nature that uniformity is the desideratum and is necessary in the interests of the nation. For instance, standards of weights and measures should be laid down by the Centre because it is in the national interest to do so. If in any sphere uniformity is not necessary but on the other hand there should be diversity and variety, it is the sphere of education.
