“We feel that even if all possible scientific questions be answered, the problems of life have still not been touched at all.”

“The primary question about life after death is not whether it is a fact, but even if it is, what problems that really solves.”

“For an answer which cannot be expressed the question too cannot be expressed.The riddle does not exist.If a question can be put at all, then it can also be answered.”

“The real question of life after death isn't whether or not it exists, but even if it does what problem this really solves.”

“In philosophy it is always good to put a question instead of an answer to a question. For an answer to the philosophical question may easily be unfair; disposing of it by means of another question is not.”

“The problems are solved, not by giving new information, but by arranging what we have known since long.”

“Logic takes care of itself; all we have to do is to look and see how it does it.”
