"“By virtue of its simplicity,” Einstein realized, the idea of a personal God was “accessible to the most undeveloped mind,” and accessibility had its advantages. “But on the other hand,” he continued, “there are decisive weaknesses attached to this idea in itself, which have been painfully felt since the beginning of history.”103 Einstein’s acceptance of traditional faith was not a matter of tolerance, then, or even agnosticism, but rather resignation. In a letter written in 1920, he lamented that “even nowadays, eliminating the sacred traditions would still mean spiritual and moral impoverishment—as gross and ugly as the attitude and actions of the clergy may be in many respects.”104 And so, although he rejected monotheism in principle, he accepted people’s faith in a personal God as a necessary evil (or expedient) in practice. Some scholars, such as Max Jammer and the theologian Alister McGrath, have interpreted this stance as tacit support for traditional religion, but “better than nothing” is pretty faint praise.105
Ultimately, what worried Einstein wasn’t unbelief in God, but the absence of any big-picture perspective at all. He abhorred nihilism, not atheism. For him, a life lived without a sense of wonder and purpose was no life at all. “What is the meaning of human life, or for that matter, of the life of any creature?” he once asked. “To know an answer to this question means to be religious.… The man who regards his own life and that of his fellow creatures as meaningless is not merely unhappy but hardly fit for life.”106
As a culture, we might feel that we’ve adequately assimilated the hard lessons of physics and philosophy over the last few hundred years: God is dead, Nature is probabilistic, nothing is true, everything is permitted. And perhaps we have become sufficiently skeptical, secular, and cynical. But a naïve, rather nasty nihilism was not the endgame Einstein had in mind. His third-phase spirituality was more than just “sexed-up atheism” or “watered-down theism.”107 Einstein saw that a genuine sense of awe was in short supply among complacent believers and fanatical atheists alike. And this ephemeral feeling was so important to him that he would make wonder the central axis around which his entire spirituality revolved."
