 Critics of hard incompatibilism include both compatibilists and libertarians. See, for example, the entries on  compatibilism,  incompatibilist (nondeterministic) theories of free will, and  arguments for incompatibilism.  I will here only briefly discuss one possible compatibilist reply—the attempt to block the conclusion of the manipulation argument, one of the main arguments employed by hard incompatibilists and other incompatibilists.
