Smuts was for most of his political life a vocal supporter of segregation of the races, and in 1929 he justified the erection of separate institutions for blacks and whites in tones prescient of the later practice of apartheid:
The old practice mixed up black with white in the same institutions, and nothing else was possible after the native institutions and traditions had been carelessly or deliberately destroyed. But in the new plan there will be what is called in South Africa "segregation"; two separate institutions for the two elements of the population living in their own separate areas. Separate institutions involve territorial segregation of the white and black. If they live mixed together it is not practicable to sort them out under separate institutions of their own. Institutional segregation carries with it territorial segregation.
In general, Smuts' view of Africans was patronising, he saw them as immature human beings that needed the guidance of whites, an attitude that reflected the common perceptions of most non-Africans in his lifetime. Of Africans he stated that:
These children of nature have not the inner toughness and persistence of the European, not those social and moral incentives to progress which have built up European civilization in a comparatively short period.
