"That the sun will not rise tomorrow is no less intelligible a proposition, and implies no more contradiction, than the affirmation, that it will rise"

This quote by David Hume is referring to the concept of apprehension. He is recommending that it is simply as affordable to think that the sun will not increase tomorrow as it is to believe that it will. Hume is indicating that it is impossible to understand for specific what will happen in the future, which it is difficult to prove either declaration. He is recommending that it is impossible to be specific of anything, and that we need to be open to the possibility of either outcome. This quote is a reminder that we must not be too fast to make presumptions about the future, which we need to stay open up to the possibility of any result. Hume's quote is a pointer that we ought to not be too fast to make assumptions about the future, and that we should remain available to the possibility of any outcome.
