I am a research fellow at the Institute for Frontier Areas of Psychology and Mental Health in Freiburg, Germany. I studied Psychology and Philosophy at the University of Fribourg (Switzerland) and Munich (Germany) and have a Ph.D. in Medical Psychology from the Ludwig Maximilian University of Munich. Between 2004 and 2009 I was Research Fellow at the Department of Psychiatry, University of California San Diego. My research in the field of Cognitive Neuroscience is focused on the perception of time in ordinary and altered states of consciousness. The investigation concerning the riddle of subjective time as based on the embodied self leads me to answers of what matters most, the nature of our existence as self-conscious beings.

I am a philosopher of science who has an obsession with time. People think this interest is a case of patronymic destiny, that it’s due to my last name being Callender. But the origins of “Callender” have nothing to do with time. Instead, I’m fascinated by time because it is one of the last fundamental mysteries, right up there with consciousness. Like consciousness, time is connected to our place in the universe (our sense of freedom, identity, meaning). Yet we don’t really understand it because there remains a gulf between our experience of time and the science of time. Saint Augustine really put his finger on the problem in the fifth century when he pointed out that it is both the most familiar and unfamiliar thing.

My undergraduate physics textbook asked, “What is an electric field? Is it something real, or is it merely a name for a factor in an equation which has to be multiplied by something else to give the numerical value of the force we measure in an experiment?” Here, I thought, is a good question! But the textbook said that since electromagnetic theory “works, it doesn’t make any difference" what an electric field is! Then it said, "That is not a frivolous answer, but a serious one.” I felt ashamed. But my physics teacher helpfully suggested that I “speak to the philosophers.” I am very pleased that I decided to become one!

I'm a PEN Award-winning historian of alternative spirituality and a writer-in-residence at the New York Public Library. I track the impact and substance of supernatural beliefs—a source of fascination since my Queens, NY, boyhood—in books including Occult America, The Miracle Club, and Uncertain Places. I often say that if you do not write your own history, it gets written for you—usually by people who may not care about or even understand the values that emanate from your work. Given my personal dedication to the spiritual search, I call myself a believing historian (which most historians of religion actually are). I labor to explore the lives, ideas, and practices behind esoteric spirituality.

I am a professor of philosophy at Wake Forest University, with a Ph.D. in philosophy from the University of Massachusetts at Amherst. I teach courses in the philosophy of space and time, the history of philosophy, and the philosophy of science. In addition to several authored and edited books on the philosophy of time, I have published many scholarly articles on time, perception, knowledge, and the history of the philosophy of time. I have always been attracted to the philosophy of time because time is quite simply at the root of everything: through the study of time we confront and illuminate the deepest possible questions both as to the nature of the physical world and as to the nature of human existence.

I am a professor of humanities at Johns Hopkins and have spent my career thinking, teaching, and writing about the relations between literature, philosophy, and science. Many years ago I started out thinking I would be a scientist, but then got pulled into literature and philosophy. Still, that original passion never left me. As I studied and read the great authors and thinkers from Classical Antiquity through the Middle Ages to the modern era, the big, fundamental questions of our place in the universe and the ultimate nature of reality seemed as pertinent to poets and philosophers as it is to physicists and cosmologists. 

I have time, save time, spend time, waste time, write, and teach time. I am fascinated with the question of time both as a cosmological phenomenon and as an aspect that is inseparable from our existence. I channeled this fascination into a PhD dissertation, books, and articles examining the relationship between time and human existence. But like Saint Augustine, I am still baffled by the question of time and like him: "If no one asks me, I know what it is. If I wish to explain it …, I do not know."

I write science fiction mostly. I’ve recently turned my attention to history. The shared interest is in the changing ground of human interaction. In a way, we are all aliens to each other (which is one of the chief fascinations with fiction to begin with, the psychologies involved). After 30-plus years as a writer, I am more and more drawn to work that reveals the differences and the similarities. Unique contexts throws all this into stark relief.
