“Become tolerant and resist any type of ignorance that is based on dogmas.”

Context: He who bases or thinks he bases his conduct — his inward or his outward conduct, his feeling or his action — upon a dogma or a principle which he deems incontrovertible, runs the risk of becoming a fanatic, and moreover, the moment that this dogma is weakened or shattered, the morality based upon it gives way. If the earth that he thought firm begins to rock, he himself trembles at the earthquake, for we do not all come up to the standard of the ideal Stoic who remains undaunted among the ruins of a world shattered into atoms. Happily the stuff that is underneath a man's ideas will save him. For if a man should tell you that he does not defraud or cuckold his best friend only because he is afraid of hell, you may depend upon it that neither would he do so even if he were to cease to believe in hell, but that he would invent some other excuse instead. And this is all to the honor of the human race.

Context: It could become of fundamental importance, and be not merely a transient fashion of the present, if more and more people today would make a daily habit of devoting an hour, or at least a few minutes, to meditation. As a result of the meditative penetration and broadening of the natural-scientific world view, a new, deepened reality consciousness would have to evolve, which would increasingly become the property of all humankind. This could become the basis of a new religiosity, which would not be based on belief in the dogmas of various religions, but rather on perception through the "spirit of truth." What is meant here is a perception, a reading and understanding of the text at first hand, "out of the book that God's finger has written" (Paracelsus), out of the creation.
The transformation of the objective world view into a deepened and thereby religious reality consciousness can be accomplished gradually, by continuing practice of meditation. It can also come about, however, as a sudden enlightenment; a visionary experience. It is then particularly profound, blessed, and meaningful. Such a mystical experience may nevertheless "not be induced even by decade-long meditation," as Balthasar Staehelin writes. Also, it does not happen to everyone, although the capacity for mystical experience belongs to the essence of human spirituality.

The Tragic Sense of Life (1913), XI : The Practical Problem
Context: My conduct must be the best proof, the moral proof, of my supreme desire; and if I do not end by convincing myself, within the bounds of the ultimate and irremediable uncertainty of the truth of what I hope for, it is because my conduct is not sufficiently pure. Virtue, therefore, is not based upon dogma, but dogma upon virtue, and it is not faith that creates martyrs but martyrs who create faith. There is no security or repose — so far as security and repose are obtainable in this life, so essentially insecure and unreposeful — save in conduct that is passionately good.
