Scientific progress in the 20th century has shown that the structure of the world is hierarchical. A philosophical analysis of the hierarchy will bear obvious significance for metaphysics and philosophy in general. Jonathan Schaffer’s paper, “Is There a Fundamental Level?”, provides a systematic review of the works in the field, the difficulties for various versions of fundamentalism, and the prospect for the third option, i.e., to treat each level as ontologically equal. The purpose of this paper is to provide an (...) argument for the third option. The author will apply Aristotle’s theory of matter and form to the discussion of the hierarchy and develop a theory of form realism, which will grant every level with “full citizenship in the republic of being.” It constitutes an argument against ontological and epistemological reductionism. A non-reductive theory of causation is also developed against the fundamental theory of causation. (shrink)

This paper is to spell out a version of perception dualism, whose ontological description of the mind-body relation is stronger than property dualism but weaker than substance dualism, that is, to define mental events as perceptions from an internal point of view and physical events as perceptions from an external point of view, then, the author set out to tackle some long-persisting ontological issues in philosophy of mind, such as the psycho-physical interaction, the criterion of mind, the clash between free (...) will and natural necessity, Benjamin Libet’s Experiment. It also recovers some of the observations and conclusions achieved byCartesian internalism and Leibniz’s parallelism. Since perception is the most essential feature of mind, while defining mental and physical events in terms of perception, the author also develops a philosophical theory of perception. (shrink)
