So you never plan anything unless you are absolutely certain of the facts that you are basing you plan on.
Well obviously, I, like you, plan on the available facts, then make the best bet. What neither of us do is plan our day based on an un-evidenced belief about what we would like to be true regardless of the facts before us.
You would not plan your picnic on a belief. You, like everyone else on the planet, would look out of the window, look at the forecast and then decide.
What else in your life do you think you do purely on belief?
