Some key points in this whole thing:

 Dominant forms of knowledge have been constructed largely from the experiences of the most powerful, ie: those straight, white, western males who historically have had the most access to systems of education and communication.

One can and must identify the discourses (how we talk about things) that support and maintain white supremacy and patriarchy...

Power and knowledge is inextricably linked. We still have language and discourses upholding unjust power structures. Oppressors (usually, and especially, straight, wealthy, western, white males) still perpetuate their privilege and “power-knowledge” through discourse.

There is really only one objective reality: ie- systems of power and privilege exist. Almost everything else is a social, cultural and  linguistic construct.

Women, people of colour and LGBT persons often have unwritten, untold and subordinated truths, which can be a source of knowledge in pursuit of social justice. Those who are most oppressed have access to a deeper and more authentic knowledge about life and society; in fact, a superior knowledge of the world......Western science is just one way of knowing the world and it is corrupted by power. Multiple knowledges exist and they are related to identify; for example, being a black, trans woman.

To repeat, a lot can be understood by thinking about and reflecting on the relationship between knowledge and power. We have to admit that a lot of the “truths” and “knowledge” in the West have been and often still are relativistic and bourgeois creations. We have to acknowledge that most of the so-called truths about the world and human nature are not absolute truths but the past ideological assertions of dead, white, western males and later the ideological assertions of the patriarchal corporate state. We have to think of  “truth”, “reality” and “categories” as being constructed according to the power interests of groups advantaged by such constructions, ie: white, wealthy, straight, western males.

All the above, some believe, is drawing simplistic and extreme conclusions from the following (which almost everyone would acknowledge as being true, or true to an extent) : There IS no doubt that humans can find it very hard to be objective and rational. Most of us as individuals and or as social, ethnic, racial or religious groups have been guilty of reconstructing our own histories in a way that makes us the hero and the other party the villain; and there HAS been many instances of in which so called historical, philosophical and even scientific “truths” HAVE turned out to be heavily distorted. As well, power elites in every society and every era have tried to use the slipperiness of language to try to foist their construction of “truth” on to minorities........BUT .......however  (to be continued)
