Soul

". I mean the soul simply as shorthand for the seismic core of personhood from which our beliefs, our values, and our actions radiate."

On Boredom

"In a section of his 1843 masterwork Either/Or: A Fragment of Life (public library), which also gave us Kierkegaard on our greatest source of unhappiness, the Danish philosopher defines boredom as a sense of emptiness and examines it not as an absence of stimulation but as an absence of meaning — an idea that also explains why it’s possible, today more than ever, to be overstimulated but existentially bored."
