Amen. I too am curious (sic) why any rational person would want to bury a fascinating subject like curiosity by entangling it with obsolete fantasy-based sophistry like freudianism. Employing but a wee bit of fair-minded imagination instead would surely yield more fruitful and substantial insights.
And was there a book review hiding beneath all that noxious palaver? TL-DR. I'd genuinely like to know. Curiosity deserves better inquiry and illumination than the few books I've seen on the topic.
