Master's tools, master's house?

A friend posed a question yesterday: can anything revolutionary actually come out of the academy?

This question brings forth a overwhelming myriad of questions for me.
-What did my education provide for me? Why do I feel that its impact was so intense?
-What attitude did I bring into my education?
-What change do I expect to be able to bring out of teaching?
-Am I just feeding the machine and allowing myself to be used as a tool of oppression and capitalism if I continue pursuing education?
-Can change really be affected from the high tower of academics? Or is that a white, middle-class, liberal illusion that we like to feed ourselves?
-Is revolution what I want to inspire? What does revolution even look like?
-Is there really any hope?
-Jeez-o-peets, why is this so complicated?

Audre Lorde writes that you can't dismantle the master's house with the master's tools. Do we have any tools that aren't formed and influenced by the master? What do you do with this idea when you are complicit in the structures that form the master's house-sexism, racism, classism, colonialism, capitalism?

All I've got at this point is questions- more and more questions.

Someone, somewhere told me that the point of further education is really just to increase the questions. So maybe I'm doing something right? Maybe...who knows.
