“Matters of religion should never be matters of controversy. We neither argue with a lover about his taste, nor condemn him, if we are just, for knowing so human a passion.”

2012, Re-election Speech (November 2012)
Context: Democracy in a nation of 300 million can be noisy and messy and complicated. We have our own opinions. Each of us has deeply held beliefs. And when we go through tough times, when we make big decisions as a country, it necessarily stirs passions, stirs up controversy. That won't change after tonight, and it shouldn't. These arguments we have are a mark of our liberty. We can never forget that as we speak people in distant nations are risking their lives right now just for a chance to argue about the issues that matter, the chance to cast their ballots like we did today. But despite all our differences, most of us share certain hopes for America's future.

A Sketch of a Personalistic Universe (1936)
Context: There is neither spirit nor matter in the world; the stuff of the universe is spirit-matter. No other substance but this could produce the human molecule. I know very well that this idea of spirit-matter is regarded as a hybrid monster, a verbal exorcism of a duality which remains unresolved in its terms. But I remain convinced that the objections made to it arise from the mere fact that few people can make up their minds to abandon an old point of view and take the risk of a new idea. … Biologists or philosophers cannot conceive a biosphere or noosphere because they are unwilling to abandon a certain narrow conception of individuality. Nevertheless, the step must be taken. For in fact, pure spirituality is as unconceivable as pure materiality. Just as, in a sense, there is no geometrical point, but as many structurally different points as there are methods of deriving them from different figures, so every spirit derives its reality and nature from a particular type of universal synthesis.

We The Living (1936)

Source: My Several Worlds (1954), p. 208
Context: The wild winds had been sown and the whirlwinds were gathering... and I was reaping what I had not sown... None of us could escape the history of the centuries before any of us had been born, and with which we had nothing to do. We had not, I think, ever committed even a mild unkindness against a Chinese, and certainly we had devoted ourselves to justice for them, we had taken sides against our own race again and again for their sakes, sensitive always to injustices which others had committed and were still committing. But nothing mattered today, neither the kindness nor the cruelty. We were in hiding for our lives because we were white.

As quoted in Approaching God : How to Pray (1995) by Steve Brown, p. 94
Context: Spirituality means waking up. Most people, even though they don't know it, are asleep. They're born asleep, they live asleep, they marry in their sleep, they breed children in their sleep, they die in their sleep without ever waking up. They never understand the loveliness and the beauty of this thing that we call human existence. You know — all mystics — Catholic, Christian, non-Christian, no matter what their theology, no matter what their religion — are unanimous on one thing: that all is well, all is well. Though everything is a mess, all is well. Strange paradox, to be sure. But, tragically, most people never get to see that all is well because they are asleep. They are having a nightmare.
