Toughness Affects Learning

Abstract

Freud was right about some things. Therefore, usually without directly referencing him, modern researchers are dusting off a few of his previously disparaged psychoanalytic concepts. After a fall, the mighty are sometimes resurrected, or at least propped up a bit. To be sure, Freudian concepts like the unconscious, and libido, look different in the 21st century than they did a century earlier. I will not play with the unconscious here (as far as I know, but with the unconscious, who can be sure?). Instead, I focus on mental energy—a stepchild of libido.
