"The Impossible Generalized Man today is the critic who believes in loving those unworthy of love as well as those worthy - yet believes this only insofar as no personal risk is entailed. Meaning he loves no one, worthy or no. This is what makes him impossible"

This quote by Nelson Algren talks with the suggestion of the "Impossible Generalized Man" - an individual that believes in liking all individuals, regardless of their value, but just if it does not involve any personal danger. In other words, this person likes no one, deserving or not. This is what makes them difficult, as it is difficult to enjoy everybody without any personal risk. Algren is recommending that this kind of individual is a doubter, as they are evaluating people based on their worthiness of love. This quote speaks with the suggestion that love is not something that can be offered with no individual threat, which it is difficult to love every person with no personal risk. It also speaks with the idea that love is something that should be offered to those that deserve it, and not just to those that are not.
