Episode 54 - Consciousness and Memory with Prof Xeno Rasmusson
Consciousness is a difficult concept to both explain and understand. In the simplest sense the word is synonymous with "wakefulness" or maybe "awareness" but it is so much more than that. It is an enduring mystery of neuroscience and how exactly consciousness occurs from the firing of many neuronal connections in the brain is as yet a mystery.
When I attempt to focus in on the experiences of consciousness I'm almost immediately distracted by something else: time. Our perception of time is based on our experiences of consciousness. In each moment of "the present" what we think of as "ourselves" is informed by past moments conjured from our memories. We know that what is the present will eventually be a moment that we think of as the past. We know there will become a future moment that we live inside as the present only because it has happened so many times before. The only way we know about there being a future is because we have experienced things in the past and we believe that we will again. When thinking about this, I have to ask a question: is it possible to conceive of a conscious being that does not record its own experiences?
One definition I once conjured for consciousness was that it's the feeling of memory being written inside the brain. This is probably not entirely true but, in the way that we don't fully understand how consciousness truly works, it's likely not entirely false either.
A person's sense of "self" is also wrapped up in this consciousness burrito. Who you are as a person is tightly tied to who you have been in the past. Your experiences form some direction for where you're headed next. With this in mind it becomes even more difficult to imagine a conscious being that has no memories of its own experiences. How could such a creature form a sense of self? How could it ever know that its current self was in any way tied to its past self? Without memories of the past, would such a creature even know *about* the passage of time?
All of this brings me back to a (now old) movie called Total Recall. Arnold Schwarzenegger is living an average life on Earth (being married to Sharon Stone is average? anyways) when he discovers that some of his memories are missing. He sets out to find them and, on the journey, discovers additional things that "he" has done. **Spoiler alert** In the end he rejects his former self and the memories attached to them. Could it have been possible for anyone to be comfortable enough with themselves and their lives (being married to Sharon Stone) to *not* be distracted by the idea that there is something about their "self" that's being hidden from them?
