Henri Bergson's philosophy is centered on forming a concept of lived time or durée, which he saw as a process of continuous variation and flux. He believed that the study of time should be the foundation of philosophy. By studying time, we find an integration of concrete, infinite, qualitative multiplicity within consciousness that we should use to understand the essence of reality. I show that his insights into the reality of duration come directly from a metaphysical or phenomenological interpretation of (...) integral and differential calculus. Drawing on the recently published lectures from 1902–1905, I show how An Introduction to Metaphysics schematizes the methodology of Matter and Memory and Time and Free Will by means of this mathematical analogy. To Bergson, the concepts of calculus are not mere metaphors; they unleash certain metaphysical implications that problematize the mind's relation to movement, life, consciousness, time, and consequently, reality itself.

Bergson's integral empiricism is a philosophical approach that aims to harmonize the scientific study of nature with the experience of consciousness. Bergson drew heavily on the basic concepts of calculus in framing his philosophy of intuition. He did not merely use calculus metaphorically to describe processes and organizational patterns of consciousness. Instead, he studied the thought processes actually involved in calculus and showed that they are intimately connected to how we think about change more generally. I propose a distinction between (...) derivative empiricism, i.e., reductionism, and integral empiricism that incorporates the study of the mind by the mind. The method involves the invention of a new kind of knowledge that is not based on generalization or abstraction but rather on the integration of experience. This is predicated on a study of the act of integration in consciousness that underpins our ability to think and do philosophy. (shrink)

The role of intensity in Aristotelian philosophy is obscure. The problem has historically been approached through his logic and categorical sense of motion. Scholars have largely failed to consider the role of intensity in psychology and ethics, the consideration of which greatly clarifies the situation. To this end, I identify three types of intensity present in the corpus Aristotelicum: comparative, modal, inceptive. I show that the intensity of physical contraries is primary in nature but is different from those found in (...) organic processes. I then show that the intensifications found in life, produced by the soul, are of paramount importance to Aristotle’s philosophy. Inceptive intensity is the backbone of psychical activities: concoction, sensation, pleasure, perception, effort, attention, and self-awareness. I outline two essential characteristics of these intensifications: (1) they imply an intransitive causality that is intrinsic to the entity’s nature or form; (2) that they involve an interaction of many parts which mutually amplify each other so that the whole is beyond (irreducible to) the totality of the parts. I end by comparing Aristotle’s views on intensity to contemporary ideas of emergence: feedback, holism, intentionality, and supervenience. (shrink)

There was a long and lively debate in Ancient Greece on the nature of music, spanning philosophy, cosmology, and psychology. Peripatetic musicology based its understanding of the nature of music on philosophical principles derived from Aristotle’s psychology in order to address debates among their predecessors, primarily to shift the focus away from the physical sounds or their mathematical ratios, towards the investigation of the psyche, which I show was a sort of proto-phenomenology. Music involves a voluntary activity accompanied by a (...) natural joy. This joy grows and intensifies the energeia of the psyche. The nature of music is related directly to the nature, essence, or activity, of the psyche. (shrink)
