Your doctrine of immortality supposes consciousness after death. I do not believe it, otherwise the soul would be conscious under chloroform, or when the body is knocked senseless in an accident.

The Catholic Answers

This fact does not invalidate the reasons given already, and is also easily explained. The soul whilst in a state of union with the body operates by using the faculties of that body. If the sense instruments are incapacitated, the soul can no longer operate adequately whilst united to the body. But once released from the body, its intelligence and will and power to love at once assert themselves. Hydrogen and oxygen unite to form a drop of water. They can operate as water only whilst united. Hydrogen is there, but it cannot operate as hydrogen until released from the union. Soul and body make one human being. And both elements must be fit to co-operate in the activities of a bodily human being. The soul cannot operate separately as a distinct unit whilst still united. But once released, it can operate independently every bit as much as hydrogen when released from its essential union with oxygen to form water.
