The truth us that other systems of geometry are possible, yet after all, these other systems are not spaces but other methods of space measurements. There is one space only, though we may conceive of many different manifolds, which are contrivances or ideal constructions invented for the purpose of determining space.

After reading all that has been written, and after thinking all that can be thought, on the topics of God and the soul, the man who has a right to say that he thinks at all, will find himself face to face with the conclusion that, on these topics, the most profound thought is that which can be the least easily distinguished from the most superficial sentiment.
Edgar Allan Poe
The most violent revolutions in an individual's beliefs leave most of his old order standing. Time and space, cause and effect, nature and history, and one's own biography remain untouched. New truth is always a go-between, a smoother-over of transitions. It marries old opinion to new fact so as ever to show a minimum of jolt, a maximum of continuity.
William James
To suppose such a thing possible as a society, in which men, who are able and willing to work, cannot support their families, and ought, with a great part of the women, to be compelled to lead a life of celibacy, for fear of having children to be starved to suppose such a thing possible is monstrous.
William Cobbett
