Physicists and philosophers question the validity of one of the most observed and seemingly obvious appearance in our world: that time flows. Many in the physics and philosophy communities contend that the flow of time is not a fundamental feature of the world, nor even a fact of the world, but is an illusion. As a case in point, we will consider Brian Greene’s view of time in his PBS exposition “The Elegant Universe” holding that time may not flow, the past may not be gone, the future may already exist, and that now is not special. Most people, as observers of time’s passage, might agree with the Greek philosopher Heraclitus who expressed the idea that all is change and that change occurs with the flow of time. I will explore some of the motivation and reasons given for these positions and contrast the arguments made for each viewpoint.
The schedule: a short presentation on topic of 3-D Printing, and then Stuart’s presentation for about 1 hr. plus time for questions. It is necessary to register beforehand to be admitted.
CV: Stuart Kurtz graduated from MIT with an SB in Chemical Engineering and from Princeton with an MS degree in Polymer Engineering and an MA and PhD. in Chemical Engineering. He taught at RPI and in Brazil as Professor Titular in Materials Engineering. This was followed by a research career in industry accumulating around 30 patents and publishing at least a few good papers. He now focuses on Philosophy of Science and Physics and climbing mountains because they are there. He has spoken to the Lyceum Society many times; most recently in January, 2018 he spoke on the topic: Lessons from Science Lysenko, Velikovsky and the Demarcation Problem; In February, 2018 he spoke on Geoengineering for Climate Change Mitigation. In December, 2018 he reviewed the Nobel Prize in Physics for that year.
When someone is in a conscious state, must they be aware of that state? The Buddhist philosopher Dignāga offers a brilliant route to answering this question by leveraging the role awareness might play as a constraint on memory. I begin by clarifying his strategy and what conclusions it might be used to establish. Here I examine different candidate directions of explanation between consciousness and inner awareness. I interpret the metaphor of consciousness as a lamp that lights itself, and use the metaphor to distinguish between his view and contemporary higher-order theories of consciousness. I then turn to explain why the memory argument fails. The first main problem is that, contrary to Dignāga’s contemporary defenders, there is no good way to use the argument to reach a conclusion about all conscious states. The second main problem is that the proposed awareness constraint on memory is highly problematic, in tension both with ancient objections as well as current psychology.
