I am not worried if scientists go and explain everything. This is for a very simple reason: an impala sprinting across the Savannah can be reduced to biomechanics, and Bach can be reduced to counterpoint, yet that does not decrease one iota our ability to shiver as we experience impalas leaping or Bach thundering. We can only gain and grow with each discovery that there is structure underlying the most accessible levels of things that fill us with awe. But there is an even stronger reason why I am not afraid that scientists will inadvertently go and explain everything — it will never happen. While in certain realms, it may prove to be the case that science can explain anything, it will never explain everything. As should be obvious after all these pages, as part of the scientific process, for every question answered, a dozen newer ones are generated. And they are usually far more puzzling, more challenging than than the prior problems. This was stated wonderfully in a quote by a geneticist named Haldane* earlier in the century: ‘Life is not only stranger than we imagine, it is stranger than we can imagine.’ We will never have our flames extinguished by knowledge. The purpose of science is not to cure us of our sense of mystery and wonder, but to constantly reinvent and reinvigorate it.
