Is the mind the cause of change and of differences in physical outcomes, as Socrates states in the conclusion of the Phaedo, or is it like software responding to the physical hardware of the body? The mind’s role was featured as members of the Toronto Philosophy and Calgary Philosophy Meetup groups met on February 20, 2022 to finish reading Plato’s dialogue that ends with the execution of Socrates. What does the evolving science of quantum mechanics have to say about the role of the mind as the observer and its effect on the physically observed? What is the cause of the mind itself, and which appeared first in the universe – mind or matter? Our discussion proceeded to address Plato’s theory of Forms, based on the principle that things come to be in opposites which are indestructible and incapable of either increase or decrease. Socrates applies this principle in stating that the Form of life itself is the soul and, since the opposite of life is death, the soul as the cause of life is necessarily deathless and therefore eternal. The proposition of an immortal soul remains contentious, and we will explore it and the nature of the Forms further in our upcoming sessions on Plato’s Sophist.
