I know such view is quite common, but if I want to avoid statistical physics, it is hard to introduce entropy first and then temperature as a derived concept. Historically, the temperature is assumed first and the entropy is derived, by the consideration of Carnot cycles - this is the way entropy was discovered. So I wonder whether there is some non-statistical, non-entropic argument for the positive temperature, which would make the historical path more sensible.
