The greatest disaster of the nineteenth century was this: that men began to use the word 'spiritual' as the same as the word 'good.' They thought that to grow in refinement and uncorporeality was to grow in virtue. When scientific evolution was announced, some feared that it would encourage mere animality. It did worse: it encouraged mere spirituality. It taught men to think that so long as they were passing from the ape they were going. But you can pass from the ape and go to the devil.
