For example, the events of the past year have shaped all of us, but the future years are ours to shape. We all perceive the Arrow: we remember the start of the pandemic, but we don't "remember" or even know when it will end in the future. We have hopes about the future, but must simply accept and learn from what has happened in the past. Where do these differences come from? How do they arise in human psychology? Do they have an origin in the physical nature of space and time? What can reflecting on the difference between the past and the future tell us about our place in the post-pandemic world?
