This volume brings together philosophers and psychologists to investigate the phenomenon of transformative change and a host of fascinating questions it prompts. Taking their departure from seminal work on transformative choice and experience by L. A. Paul and Edna Ullmann-Margalit, the authors pursue fundamental questions concerning the nature of rationality, the limits of the imagination, and the metaphysics of the self. They also strike out into new areas, including value theory, aesthetics, moral and political philosophy. Several chapters present the results of experimental investigation into the psychology of transformation, self-concept, and moral learning.

Ordinary judgments about personal identity are complicated by the fact that phrases like “same person” and “different person” have multiple uses in ordinary English. This complication calls into question the significance of recent experimental work on this topic. For example, Tobia (2015) found that judgments of personal identity were significantly affected by whether the moral change described in a vignette was for the better or for the worse, while Strohminger and Nichols (2014) found that loss of moral conscience had more of an effect on identity judgments than loss of biographical memory. In each case, however, there are grounds for questioning whether the judgments elicited in these experiments engaged a concept of numerical personal identity at all (cf. Berniūnas and Dranseika 2016; Dranseika 2017; Starmans and Bloom 2018). In two pre-registered studies we validate this criticism while also showing a way to address it: instead of attempting to engage the concept of numerical identity through specialized language or the terms of an imaginary philosophical debate, we should consider instead how the identity of a person is described through the connected use of proper names, definite descriptions, and the personal pronouns “I”, “you”, “he”, and “she”. When the experiments above are revisited in this way, there is no evidence that the differences in question had an effect on ordinary identity judgments.

Do biological species have essences? The debate over this question in philosophy of biology exhibits fundamental confusion both between and within authors. In What to Salvage from the Species Essentialism Debate, I argue that the best way forward is to drop the question and its terms in order to make progress on two issues: how to individuate species taxa; and how to make sense of changes in explanatory frameworks across the Darwinian historical divide. I further argue that a primary motivation for anti-essentialism, biological variation, matters differently to each project. Anti-essentialism in the philosophy of biology has inspired influential rejections of the idea that there is such a thing as human nature. In More Bark than Bite, I show that the arguments are significantly weaker than supposed. Moreover, none of the weighty consequences thought to follow from any genuine sense in which there is no human nature, actually do follow. The evolution-based denial of human nature has little to contribute to inquiries into the human condition, both philosophical and scientific. Decisions about whether to undergo experiences that could change the very preference-base on which the choice is made are “transformative”. L. A. Paul argues that transformative decisions present a problem for standard decision theory when approached in a way that leans on evaluations of the experiential consequences of the choices. Her solution proposes that we approach such decisions by asking ourselves how much we value the kind of discovery involved in transformative experience. In Shifting Attention on Transformative Choice, I present two problems for her solution and offer an alternative. Transformative decisions may be rationally approached by asking ourselves how much we judge the activities on the other side of transformation to be worthwhile. This proposal helps make better sense of our relationship to experiential consequences of transformation, which is more flexible than Paul acknowledges.
