does "never" applies both for "think" and "is so intensely consciouss"?
It was this etheric body which Davis saw emerging from its poor outworn envelope of protoplasm, which finally lay empty upon the bed like the shrivelled chrysalis when the moth is free. The process began by an extreme concentration in the brain, which became more and more luminous as the extremities became darker. It is probable that man never thinks so clearly, or is so intensely conscious, as he becomes after all means of indicating his thoughts have left him. Then the new body begins to emerge, the head disengaging itself first. Soon it has completely freed itself, standing at right-angles to the corpse, with its feet near the head, and with some luminous vital band between which corresponds to the umbilical cord.
