Criticisms Exponents of analytic philosophy, which has been the dominant form of Anglo-American philosophy for most of the last century, have criticised Hegel's work as hopelessly obscure. Existentialists also criticise Hegel for ultimately choosing an essentialistic whole over the particularity of existence. Epistemologically, one of the main problems plaguing Hegel's system is how these thought determinations have bearing on reality as such. A perennial problem of his metaphysics seems to be the question of how spirit externalises itself and how the concepts it generates can say anything true about nature. At the same time, they will have to, because otherwise Hegel's system concepts would say nothing about something that is not itself a concept and the system would come down to being only an intricate game involving vacuous concepts. Schopenhauer Schopenhauer noted that Hegel created his absolute idealism after Kant had discredited all proofs of God's existence. The Absolute is a non-personal substitute for the concept of God. It is the one subject that perceives the universe as one object. Individuals share in parts of this perception. Since the universe exists as an idea in the mind of the Absolute, absolute idealism copies Spinoza's pantheism in which everything is in God or Nature. Moore and Russell Famously, G. E. Moore’s rebellion against absolutism found expression in his defense of common sense against the radically counter-intuitive conclusions of absolutism (e.g. time is unreal, change is unreal, separateness is unreal, imperfection is unreal, etc.). G. E. Moore also pioneered the use of logical analysis against the absolutists, which Bertrand Russell promulgated and used in order to begin the entire tradition of analytic philosophy with its use against the philosophies of his direct predecessors. In recounting his own mental development Russell reports, "For some years after throwing over [absolutism] I had an optimistic riot of opposite beliefs. I thought that whatever Hegel had denied must be true." (Russell in Barrett and Adkins 1962, p. 477) Also: Pragmatism Particularly the works of William James and F. C. S. Schiller, both founding members of pragmatism, made lifelong assaults on Absolute Idealism. James was particularly concerned with the monism that Absolute Idealism engenders, and the consequences this has for the problem of evil, free will, and moral action. Schiller, on the other hand, attacked Absolute Idealism for
