 In this vein, for example, he tried to lay new foundations for the theory of value by going back to value-feelings (emotions) as its psychological basis. But although Meinong had constantly recognized the fundamental role of psychology in philosophy, he became more and more an opponent of psychologism. His switch to an objectivistic account of a theory of value (1912) and his distinction between the “psychological” (mental) content and the object of a mental act, introduced in 1899, became hallmarks of his anti-psychologism.
