It has been suggested that "Alinsky is to community organizing as Freud is to analysis." Having written about it, "philosophized about it, and provided the first set of rules", he was the first to call attention to community organizing "as a distinct program, with a life and literature of its own, separate from any particular cause such as the union movement or Populism." His biographer Sanford Horwitt credits Alinsky "more than anybody ... for demonstrating that community organizing could be a lifelong career."
