Re: Aliens of Trek Lit, Chapter Five - Efrosians!
But in general it's difficult to find an alien species who is weaker than humans.
True, though the physical superiority of other races (in lifespan, strength or sensory capacity) is usually balanced by some vague notion that humans are "special" and uniquely equipped with determination, or compassion or idealism or creativity, or some other ill-defined quality that supposedly makes up for it.
Regardless of whether humans actually come across as different from other species at all...
We are all the sum of our tears. Too little and the ground is not fertile and nothing can grow there; too much, the best of us is washed away.
