I read this several times and pondered on it quite a bit... I think it is profoundly true. Thank you -it's very clarifying... but also hard to deal with emotionally, as I grew up, studied and worked in overwhelmingly White environments in the U.K.
As Europeans in the late 15th/early 16th centuries discovered the enormous wealth of the lands beyond Europe, and compared those societies to their own sorry state - they were mostly cold, hungry, disease-ridden and war-torn - a clawing, rage-filled greed was aroused, and they felt compelled to come up with some justification for their gangster sale violence, their robbery and murder of colossal proportions. Enter their Bible-based theories of White superiority. Their God had given them dominion over all the animals, the birds and the beasts of the Earth and they reckoned, surely those 'darkies', were closer to being animals than to being human.
As an undergraduate student of 'philosophy', (a subject that was not called European Philosophy, but treated as something of universal truth and relevance) I found myself astonished that the 'Age of Enlightenment', had coincided with such beliefs becoming widespread, along with the increasingly vicious levels of exploitation that the various 'fathers' of the sciences and schools of philosophy had never deigned to question.
Trying to address this in my dissertation, I took a year out of formal study and having to attend irrelevant and boring lectures, to explore various 'schools of philosophy', on my own terms... I returned, after a full year of intensive research, and handed in my dissertation, in which Sojourner Truth interrogates the big wig names in Western philosophy.
I then received my first taste of White institutional power, as exerted by the White examiners who, to a man, wanted to award me a fail.
So it was indeed ironic, how I learnt that White power in academia does not like to have the light or reason and rationality shone upon it - just like the enslaving plantation owners of the South did not tolerate having their 'right' to own and exploit black people, challenged.
