Nitpickity case in point: were Ludwig alive today I am fairly certain he would follow my definition of red, which science easily allows me to make without even so much as having something red in the same room (and which I would give here as a completist were anyone besides myself reading these) … and were I alive a hundred years from now I like to think I, too, would be so open to seeing something from a perspective I could not fathom as I complete this post.
