“Mark this well, ye proud men of
action!” declared his countryman Heinrich
Heine. “Ye are, after all, nothing
but unconscious instruments of the men

Because of this definitional complexity,
I originally planned to invent my
own terms for these constellations of
traits. I decided against this, again for
cultural reasons: the words introvert and
extrovert have the advantage of being
well known and highly evocative. Every
time I uttered them at a dinner party or
to a seatmate on an airplane, they elicited
a torrent of confessions and reflections.
For similar reasons, I’ve used the
layperson’s spelling of extrovert rather
than the extravert one finds throughout
the research literature.
