Wonderstruck. How Wonder and Awe Shape the Way We Think

Helen De Cruz
Princeton University Press, 2024.
Wonder and awe lie at the heart of life’s most profound questions. Wonderstruck shows how these emotions respond to our fundamental need to make sense of ourselves and everything around us, and how they enable us to engage with the world as if we are experiencing it for the first time.
Drawing on the latest psychological insights on emotions, Helen De Cruz argues that wonder and awe are emotional drives that motivate us to inquire and discover new things, and that humanity has deliberately nurtured these emotions in cultural domains such as religion, science, and magic. Tracing how wonder and awe unify philosophy, the humanities, and the sciences, De Cruz provides new perspectives on figures such as Plato, Aristotle, Adam Smith, William James, Rachel Carson, Maurice Merleau-Ponty, Jean-Paul Sartre, and Abraham Heschel. Along the way, she explains how these singular emotions empower us to be open-minded, to experience joy and hope, and to be resilient in the face of personal troubles and global challenges.
Taking inspiration from Descartes’s portrayal of wonder as “that sudden surprise of the soul,” this illuminating book reveals how wonder and awe are catalysts that can help us reclaim what makes life worth living and preserve the things we find wonderful and valuable in our lives.

The Challenge of Evolution to Religion

Johan De Smedt and Helen De Cruz
Cambridge University Press (Cambridge Elements series), 2020.
This Element focuses on three challenges of evolution to religion: teleology, human origins, and the evolution of religion itself. First, religious worldviews tend to presuppose a teleological understanding of the origins of living things, but scientists mostly understand evolution as non-teleological. Second, religious and scientific accounts of human origins do not align in a straightforward sense. Third, evolutionary explanations of religion, including religious beliefs and practices, may cast doubt on their justification. We show how these tensions arise and offer potential responses for religion. Individual religions can meet these chall enges, if some of their metaphysical assumptions are adapted or abandoned.

Religious Disagreement

Helen De Cruz
Cambridge University Press (Cambridge Elements series), 2019.
This Element examines what we can learn from religious disagreement, focusing on disagreement with possible selves and former selves, the epistemic significance of religious agreement, the problem of disagreements between religious experts, and the significance of philosophy of religion. Helen De Cruz shows how religious beliefs of others constitute significant higher-order evidence. At the same time, she advises that we should not necessarily become agnostic about all religious matters, because our cognitive background colors the way we evaluate evidence. This allows us to maintain religious beliefs in many cases, while nevertheless taking the religious beliefs of others seriously.

A Natural History of Natural Theology

Helen De Cruz and Johan De Smedt
MIT Press, 2015.
Questions about the existence and attributes of God form the subject matter of natural theology, which seeks to gain knowledge of the divine by relying on reason and experience of the world. Arguments in natural theology rely largely on intuitions and inferences that seem natural to us, occurring spontaneously—at the sight of a beautiful landscape, perhaps, or in wonderment at the complexity of the cosmos—even to a nonphilosopher. In this book, Helen De Cruz and Johan De Smedt examine the cognitive origins of arguments in natural theology. They find that although natural theological arguments can be very sophisticated, they are rooted in everyday intuitions about purpose, causation, agency, and morality. Using evidence and theories from disciplines including the cognitive science of religion, evolutionary ethics, evolutionary aesthetics, and the cognitive science of testimony, they show that these intuitions emerge early in development and are a stable part of human cognition.
De Cruz and De Smedt analyze the cognitive underpinnings of five well-known arguments for the existence of God: the argument from design, the cosmological argument, the moral argument, the argument from beauty, and the argument from miracles. Finally, they consider whether the cognitive origins of these natural theological arguments should affect their rationality.

Avatar: The Last Airbender and Philosophy

Edited by Helen De Cruz and Johan De Smedt
Wiley Blackwell (The Blackwell Philosophy and Pop Culture Series), 2023. This book contains public philosophy essays that reflect on the cartoon show Avatar: The Last Airbender
A growing body of evidence from the sciences suggests that our moral beliefs have an evolutionary basis. To explain how human morality evolved, some philosophers have called for the study of morality to be naturalized, i.e., to explain it in terms of natural causes by looking at its historical and biological origins. The present literature has focused on the link between evolution and moral realism: if our moral beliefs enhance fitness, does this mean they track moral truths? In spite of the growing empirical evidence, these discussions tend to remain high-level: the mere fact that morality has evolved is often deemed enough to decide questions in normative and meta-ethics. This volume starts from the assumption that the details about the evolution of morality do make a difference, and asks how. It presents original essays by authors from various disciplines, including philosophy, anthropology, developmental psychology, and primatology, who write in conversation with neuroscience, sociology, and cognitive psychology.
Philosophy Illustrated. Forty-two thought experiments to broaden your mind

Helen De Cruz, Editor and Illustrator. This book contains 42 color illustrations of thought experiments and reflections by experts.
Oxford University Press, 2022.
Thought experiments are tools philosophers and scientists use to investigate how things are, without actually having to go out and experiment in the real world. This book presents forty-two philosophical thought experiments. Each thought experiment is illustrated by De Cruz (who is an illustrator as well as a philosopher), and is summarized in one or two paragraphs, which is followed by a brief exploration of its significance. Each thought experiment also includes a longer (approximately 2-page) reflection, written by a philosopher who is a specialist in the field. De Cruz's unique illustrations serve as visual and accessible starting points for classroom discussions in Intro to Philosophy courses..

Empirically Engaged Evolutionary Ethics

Advances in Religion, Cognitive Science, and Experimental Philosophy

Edited by Helen De Cruz and Ryan Nichols
Bloomsbury (Advances in Experimental Philosophy series), 2016.
Experimental philosophy has blossomed into a variety of philosophical fields including ethics, epistemology, metaphysics and philosophy of language. But there has been very little experimental philosophical research in the domain of philosophy of religion. Advances in Religion, Cognitive Science, and Experimental Philosophy demonstrates how cognitive science of religion has the methodological and conceptual resources to become a form of experimental philosophy of religion.
Addressing a wide variety of empirical claims that are of interest to philosophers and psychologists of religion, a team of psychologists and philosophers apply data from the psychology of religion to important problems in the philosophy of religion including the psychology of religious diversity; the psychology of substance dualism; the problem of evil and the relation between religious belief and empathy; and the cognitive science explaining the formation of intuitions that unwittingly guide philosophers of religion when formulating arguments.
Bringing together authors and researchers who have made important contributions to interdisciplinary research on religion in the last decade, Advances in Religion, Cognitive Science, and Experimental Philosophy provides new ways of approaching core philosophical and psychological problems.
