Philosophy teaches us and unsettles us by confronting us with what we already know. There is an irony - it teaches us what we already know. It works by taking what we know from familiar unquestioned settings and making it strange.
Philosophy estranges us from the familiar, not by supplying new information but by inviting and provoking a new way of seeing.
Here is the risk: once the familiar turns strange, it is never quite the same again. Self-knowledge is like lost innocence. However unsettling you find it, it can never be unthought or unknown.
Philosophy is a distancing, even debilitating activity.
Philosophy distances us from conventions from established assumptions and from settled beliefs.
