We live in many worlds at once. The present world, of course. We live in the near future world, where the next choice we make creates the next present world. At the same time, we can be in old haunts, and in our minds, we now inhabit past worlds. Or our minds will imagine us living in worlds that don’t exist. Imaginary worlds. Worlds where we win the lottery, where we avoid past defeats, or we turn out different than we did. We live in worlds with fears and worlds with hopes, where the invisible things around the corner or over the hill shape our world even if we never encounter it.
We inhabit the world and the objects around us, but we live in many worlds at once. For our lives in the world are a function of mind, and with our thoughts we make the worlds.
