As quoted in "Hand Book : Caution and Counsels" in The Common School Journal Vol. 5, No. 24 (15 December 1843) by Horace Mann, p. 371
Context: This is that which I think great readers are apt to be mistaken in; those who have read of everything, are thought to understand everything too; but it is not always so. Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours. We are of the ruminating kind, and it is not enough to cram ourselves with a great load of collections; unless we chew them over again, they will not give us strength and nourishment.
“Reading opens our minds and gives us knowledge. That knowledge will only be tested through our life experiences.”

Context: Our mind (and there are no individual minds — only "mind", which is the accumulation of man's knowledge and experience) has created the notion of the psyche and evolution. Only technology progresses, while we as a race are moving closer to complete and total destruction of the world and ourselves. Everything in man's consciousness is pushing the whole world, which nature has so laboriously created, toward destruction. There has been no qualitative change in man's thinking; we feel about our neighbours just as the frightened caveman felt towards his. The only thing that has changed is our ability to destroy our neighbor and his property.

Source: Reason: The Only Oracle Of Man (1784), Ch. V Section II - Containing Observations on the Providence and Agency of God, as it Respects the Natural and Moral World, with Strictures on Revelation in General
Context: There has in the different parts and ages of the world, been a multiplicity of immediate and wonderful discoveries, said to have been made to godly men of old by the special illumination or supernatural inspiration of God, every of which have, in doctrine, precept and instruction, been essentially different from each other, which are consequently as repugnant to truth, as the diversity of the influence of the spirit on the multiplicity of sectaries has been represented to be.
These facts, together with the premises and inferences as already deduced, are too evident to be denied, and operate conclusively against immediate or supernatural revelation in general; nor will such revelation hold good in theory any more than in practice. Was a revelation to be made known to us, it must be accommodated to our external senses, and also to our reason, so that we could come at the perception and understanding of it, the same as we do to that of things in general. We must perceive by our senses, before we can reflect with the mind. Our sensorium is that essential medium between the divine and human mind, through which God reveals to man the knowledge of nature, and is our only door of correspondence with God or with man.
