Explaining the Temporal Value Asymmetry
An important feature of life is the past/future value asymmetry. Not to be confused with proximal/distant discounting, the past/future value asymmetry is the fact that we prefer future rather than past preferences be satisfied. Misfortunes are better in the past, where they are “over and done,” than in the future. Some philosophers take this value asymmetry to warrant positing a radical metaphysical asymmetry between the past and future. By contrast, others contend that the value asymmetry is due to the causal asymmetry. Thanks to the causal asymmetry, there is a mechanism between future desires and future fulfilment, but no such mechanism between past desires and past fulfilment. Opponents of this view deride it as a piece of “socio-biological mythology.” Here, appealing to recent work in cognitive science, neuroscience, and evolution, a rich and powerful version of the “causal asymmetry” explanation of the value asymmetry is built.
