"For All We Know" is a classic of the Great American Songbook, music by J. Fred Coots and lyrics by Sam M. Lewis (1934).

It never ceases to amaze that something so profound could have been written that long ago. It deals with epistemology and cognitive closure. The first term is that branch of philosophy that deals with knowledge - what does it mean to say that you know something, for example, that there will be a tomorrow (think of a large object colliding with the sun)? In the lyrics you find, "Tomorrow was made for some, tomorrow may never come." The second term, cognitive closure, refers to things that are beyond and permanently out of reach of human knowledge, as expressed by, "We come, we go, like ripples on a stream." "Here today, gone today" as I like to say. And where to from there? Cognitive closure. Finally, remember that, "This may only be a dream." How do you know it isn't?
