39 | Malcolm MacIver on Sensing, Consciousness, and Imagination

Consciousness has many aspects, from experience to wakefulness to self-awareness. One aspect is imagination: our minds can conjure up multiple hypothetical futures to help us decide which choices we should make. Where did that ability come from? Today’s guest, Malcolm MacIver, pinpoints an important transition in the evolution of consciousness to when fish first climbed on to land, and could suddenly see much farther, which in turn made it advantageous to plan further in advance. If this idea is true, it might help us understand some of the abilities and limitations of our cognitive capacities, with potentially important ramifications for our future as a species.            Support Mindscape on Patreon or Paypal. Malcolm MacIver received his Ph.D. in neuroscience in 2001 from the University of Illinois and the Beckman Institute of Advanced Science and Technology. (This was after an unconventional childhood where he dropped out of school at age 9 and later talked his way into a community college program.) He is currently a professor of Mechanical Engineering, Biomedical Engineering, and Neurobiology at Northwestern University. In 2009 he was awarded the Presidential Early Career Award for Science and Engineering.
