1 " A multitude of aspects of the natural world that were considered miraculous only a few generations ago are now thoroughly understood in terms of physics and chemistry. At least some of the mysteries of today will be comprehensively solved by our descendants. The fact that we cannot now produce a detailed understanding of, say, altered states of consciousness in terms of brain chemistry no more implies the existence of a “spirit world” than a sunflower following the Sun in it’s course across the sky was evidence of a literal miracle before we knew about phototropism and plant hormones.

4 " Haldane imagined a far future when the stars have darkened and space is mainly filled with a cold thin gas. Nevertheless, if we wait long enough statistical fluctuations in the density of this gas will occur. Over immense periods of time the fluctuations will be sufficient to reconstitute a Universe something like our own. If the Universe is infinitely old, there will be an infinite number of such reconstitutions, Haldane pointed out. "
5 " Fear of death, which in some respects is adaptive in the evolutionary struggle for existence, is maladaptive in warfare. Those cultures that teach an afterlife of bliss for heroes — or even for those who just did what those in authority told them — might gain a competitive advantage. "
