Wayne Martin traces attempts to develop theories of judgment in British Empiricism, the logical tradition stemming from Kant, nineteenth-century psychologism, recent experimental neuropsychology, and the phenomenological tradition associated with Brentano, Husserl and Heidegger. His reconstruction of vibrant but largely forgotten nineteenth-century debates links Kantian approaches to judgment with twentieth-century phenomenological accounts. He also shows that the psychological, logical and phenomenological dimensions of judgment are not only equally important, but fundamentally interlinked.
