Sparseness, Immanence, and Naturalness
In the past fifteen years or so there has been a lot of attention paid to theories of “sparse” universals, particularly because of the work of D. M. Armstrong. These theories are of particular interest to those of us concerned with the distinction between natural and non-natural properties, since, as David Lewis has observed, it seems possible to analyze naturalness in terms of sparse universal...
متن کاملNaturalness and the Landscape
In this paper I review some arguments of Douglas and myself concerning the concept of naturalness in string theory. I explain why the usual argument for low energy supersymmetry do not apply in this context. An incorrect argument in [7] is corrected. The statistical properties of the Landscape of vacua are strongly biased against low energy supersymmetry.
متن کاملNaturalness (final)
In the wake of David Lewis’s seminal paper ‘New Work for a Theory of Universals’ (1983), a certain use of the word ‘natural’ has become widespread in metaphysics and beyond. In this usage, properties can be classified as more or less natural, with perfectly natural properties as a limiting case. For example, Lewis would claim that being negatively charged is much more natural than being either ...
متن کاملSupersymmetry, Naturalness and the Landscape *
We argue that the study of the statistics of the landscape of string vacua provides the first potentially predictive – and also falsifiable – framework for string theory. The question of whether the theory does or does not predict low energy supersym-metry breaking may well be the most accessible to analysis. We argue that low energy – possibly very low energy – supersymmetry breaking is likely...
متن کاملNaturalness and the Neutrino Matrix
The observed pattern of neutrino mass splittings and mixing angles indicates that their family structure is significantly different from that of the charged fermions. We investigate the implications of these data for the fermion mass matrices in grand unified theories with a type-I seesaw mechanism. We show that, with simple assumptions, naturalness leads to a strongly hierarchical Majorana mas...
