At the very least, our brains help to shape our consciousness. Can an examination of the way in which they do so help us to reconcile different visons of ourselves and of our world?  There is nothing reductionist about asking such a question: rather, McGilchrist shall suggest, it helps us to transcend the limitations of reductionism itself.  Importantly it may, for the first time, give philosophy a basis for judging certain views on the world as worthier of acceptance than others.

In this two-hour webinar, divided into two forty-minute presentation sessions followed by twenty minutes for questions and debate, Coleman will lead a discussion about the perception and interpretation of signs and symbols at it relates to music notation. The discourse will encircle Coleman’s Music: It IS Rocket Science and the many disciplines that inform the study and contemplation and performance of music. We will explore the history of music notation and contemplate the notion of music as language. Coleman will demonstrate at the piano the diverse performance outcomes that arise from the often confusing, different published editions of a single work. Webinar attendees will be encouraged to actively engage in discussion, and they will be provided with links to materials that can be perused in advance of the scheduled session.

Developments in both cosmology and particle physics suggest that our universe may just be one member of an ensemble of universes, termed the multiverse. However, there are many different versions of the multiverse proposal, so it is important to distinguish between these in assessing the plausibility of the notion. In some versions the values of the physical constants may vary across the ensemble, so this could provide a scientific basis for the suggestion that some of the constants are fine-tuned for the existence of observers. The evidence for this comes from numerous unexplained ‘coincidences’ between the constants, a notion which used to regarded as purely philosophical or even theological.

The advent of quantum mechanics in the 1920s brought with it the idea that fundamental physical processes may be stochastic which is to say random but constrained by probabilistic law. Rather than the future being determined in advance, as envisaged by Newtonian mechanics, one actual future is stochastically selected from a range of alternativepossibilities. A way to restore determinism to physics is to replace the idea of a stochastic process with that of a dendritic process where all (possible) outcomes actually occur, each in a different (branch) of a burgeoning quantum multiverse. The idea has been much discussed but remains very controversial. Paul explains some of the conceptual difficulties involved and how the idea may be linked to a non-standard materialist conception of the mind-body relation.
