This chapter examines the philosophy of T. H. Green, the initial leading figure among the absolute idealists who dominated British philosophy in the late 19th century. Green sought to establish that the existence and nature of human beings, especially of the human mind, was not susceptible of a purely empirical or scientific explanation. He claimed that the only possible explanation involved reference to the existence of an Eternal Consciousness, which was gradually realizing itself in the temporal world, more especially in the life of human beings. Further issues in his philosophy are examined, such as that things count as real only if they are in unchanging relations to each other, the difference between negative and positive freedom, the nature of moral choice, the superiority of a virtue ethic to a utilitarian one.
