Lots of interesting perspectives on this subject. Thanks Everyone
Many people have seen the movie _Memento_, in which the main character has lost the ability to remember back more than a brief period of time. Under such a scenario human consciousness can exist, albeit in a very shattered form.
But try to imagine what it would be like if you had *no* memory at all, not even for a second. If this were the case, our consciousness and awareness, and our humanity, would not exist. We would never have evolved as we did, and might instead have lives more akin to a bacteria, or a sponge, or something else with no (or limited) memory capacity.
I agree that memory is not a sense organ like the other sense organs, but isn't the fact that we remember the past, the only way we can sense time? And if so, in this way, couldn't memory still be considered a sense?
Best regards,
