4. The opinions of human beings are always proportioned to their knowledge; and the discovery of the constitution of the world around them, like all the other great discoveries of the human mind, has necessarily given a new direction to their ideas. It was inevitable that, through the action of their newly-acquired knowledge, their primitive creeds should undergo considerable modification: “heaven” has been displaced from its former position, for the region of stars, being boundless, can no longer be assigned as its locality. Where, then, is “heaven”? To this question none of the religions of the world can furnish an answer.
Spiritism has come to resolve this enigma, showing us the true destiny of human beings. Starting with the nature of humans and the attributes of God, we arrive at the conclusion: that is to say, starting with the known we arrive at the unknown, via logical deduction, without mentioning the direct observations that Spiritism permits us to realize.
