Albert Einstein deliberately and repeatedly expressed his general religious views. But what were his views of mysticism? His statements on the subject were few, relatively obscure, and often misunderstood. A coherent answer requires setting those statements in historical, cultural, and theological context, as well as examining Einstein's philosophical and religious views. Though the Einstein that emerges clearly rejected supernatural mysticism, his views of “essential” mysticism were—though largely implicit—more nuanced, more subtle, and ultimately more sympathetic than “mere appearance” suggests.
