Penetralium: An innermost or most secret part or place; the interior of a building.

I have no idea how to get my students to build a self or become a soul … and in the hundreds of faculty appointments and promotions I have participated in, we’ve never evaluated a candidate on how much he or set could accomplish it.*
Steven Pinker

We may enjoy soul-music and refer to lifeless experiences as soul-less, but we’re not so likely to think of ourselves as having souls, and yet, this is what so many are feeling towards when they sense they’re harming or breaking something inside.

*Steven Pinker, quoted in David Brooks’ The Second Mountain
