Anderson was initially influenced by the Hegelian Idealism established at Glasgow University by Edward and John Caird and further developed by Anderson’s own teacher, Henry Jones. The distinctive form of Hegelianism developed at Glasgow University is typically described as Christian Idealism, as it emphasized the dialectical development of an organic universe culminating in the realization of God. Anderson was also influenced by other Scottish philosophers such as Robert Adamson and John Burnet, although it was the Australian philosopher, Samuel Alexander, who had the most significant and permanent impact on his philosophical development. Anderson had already been exposed to the Realist writings of the early Moore and Russell, and the work of William James and the American New Realists before he attended Alexander’s Gifford lectures at Glasgow University between 1915 and 1917. These lectures, later published as Space, Time and Deity, were to exercise such a decisive influence on Anderson that he was still lecturing on them thirty years later. [Anderson 2005, 2007i] From within the history of philosophy itself, the most significant influences on him were Heraclitus, Socrates, Plato, and Hegel. He often praised Greek objectivity with its emphasis on ‘things’ and thought that almost all of modern philosophy, with its emphasis on epistemology, was irrelevant to the systematic study of philosophy, with only Hegel and Alexander being singled out for praise from the entire modern period.
