Some elements of our experience are so deeply intuitive that they appear to be brute facts about the world. Science has a habit of disabusing us of such intuitions. Notably, in the twentieth century the advent of special and general relativity assailed Newtonian notions of absolute time and space; and quantum mechanics undermined a deeply held scientific presumption of locality. In this story, however, science is on our side, defending our profound intuition that the direction of time is something immutable and that the time asymmetries observed in the unfolding of physical processes reveal an inherent feature of the universe. The vast majority of processes in the world are irreversible. We remain unsurprised upon witnessing any number of eggs breaking, but never expect to see an egg spontaneously un-break. If we observe an ice-cube melt in warm water, we do not attribute this to coincidence or chance, but rather to some natural necessity. No evidence refutes these intuitions.
