From closing lines of's course "Justice: A Journey in Moral Reasoning" (iTunes Link), by Michael Sandel.

"..., about how philosophy works and has always worked, by estranging us from the familiar, by unsettling our settled assumptions. 
I tried to warn you that once the familiar turns strange, once we begin to reflect on our circumstance it's never quite the same again. I hope you have by now experienced at least a little of this unease,  because this the tension that animates critical reflection, and political improvement and maybe even the moral life as well. ... ...

We began with the thought of Kant, that skepticism is a resting place for human reason where it can reflect upon it's dogmatic wanderings, but it is no dwelling place for permanent settlement.

From I. Kant's original text -  

"... Thus scepticism is a resting place for reason, in which it may reflect on its dogmatical wanderings and gain some knowledge of the region in which it happens to be, that it may pursue its way with greater certainty; but it cannot be its permanent dwelling-place. It must take up its abode only in the region of complete certitude, whether this relates to the cognition of objects themselves, or to the limits which bound all our cognition."  - I. Kant in Critique of Pure Reason (L)
