A paradox lies at the heart of modernity: the simultaneous demand to create ideas to make us better humans and communities, along with the contrary imperative that we criticize all ideals, especially the ones we have created. In philosophy we see this paradox most acutely in figures like Immanuel Kant, who states that we cannot know the essence of things and yet we must retain old ideas God, freedom, and the soul in order to become better and more ethical humans. Or in Friedrich Nietzsche, whose eternal recurrence, a self-created myth whose sole purpose is to get us to see the value in the everyday. This basic scheme belief and un-belief is one of the fundamental elements of modernity, manifesting itself in the philosophies of Herbert Marcuse and Michel Foucault, along with the theologies of Blaise Pascal, C.S. Lewis, William James, Sallie McFague, and Philip Clayton. How do we live out the values we know to be constructions? This question holds captiveour ability to solve public goods problems and make our lives more meaningful. Instead of seeing this paradox of modernity as self-deception or bad faith, Zachary Simpson employs cognitive and social scientific research to explain how best to realize values that we know to be false: through art, community, and ritual. In Simpson's account, the values we construct must conform to narrative, be reinforced through community, and habituated through ritual. And yet modernity has also undermined collectivity and ritual. Thus arises the second paradox of modernity: the best tools we have for realizing values are those which devalue the individual modern subject. The last part of the book attempts to make three normative points regarding modernity. First, the modern, individualist subject is insufficient to realize the very values and aspirations of modernity. We must recognize that humans are collective and communal. Second, we cannot simply create values they must arise in communities and be realized through narrative and ritual. And, third, if we are to live meaningful lives as contemporary meta-ethicists and positive psychologists argue, then such lives must include art, community, and ritual as a way to affirm and reinforce ones values. Lets Pretend is a statement about one of the dilemmas of the contemporary western world and how that dilemma is, and might be, resolved. How do we believe in the values that we know will make a better world, even if they are of our own making? We must do so, in part, by becoming less modern, by engaging with one another and imagining more. The book should serve as both an essay in the history of Western thought as well as a constructive argument about the nature of the modern epoch and what resources we have to realize the central aspirations of modernity. It aims to fill a critical lacuna in theoretical and philosophical approaches to modernity. While most texts focus on either the need for created values or the need to remedy modern subjectivity, few, if any, link the two problems together. Moreover, they do not ground their analyses in the social sciences and contemporary findings regarding the efficacy of narrative, communal action, and rituals. The book is unique, then, because it asks a central question how do we believe in what we know to be false? and because it answers this question using interdisciplinary methods that allow us to see the faultlines and paradoxes of our age.
