Guessing right for the wrong reason does not merit scientific immortality. - Stephen Jay Gould

Useful quantification is so often the key to fruitful science.

There are no shortcuts to moral insight. Nature is not intrinsically anything that can offer comfort or solace in human terms—if only because our species is such an insignificant latecomer in a world not constructed for us. So much the better. The answers to moral dilemmas are not lying out there, waiting to be discovered. They reside, like the kingdom of God, within us—the most difficult and inaccessible spot for any discovery or consensus.

Ever since paleontology established the basic outlines of the fossil record more than a century ago, we have known how poorly the old chain of being matches the history of life. Its persistence as a metaphor and even, in Jastrow’s case, as an imposed “reality” merely reflects our unwillingness to abandon comfort in the face of evidence.
