“We have discovered in this past decade that thinking, and decision, are not solely the province of the metaphysicist, but are appropriate subjects for scientific inquiry.”

Context: Books are not made to be believed, but to be subjected to inquiry. When we consider a book, we mustn't ask ourselves what it says but what it means...

Context: We think ourselves possessed, or, at least, we boast that we are so, of liberty of conscience on all subjects, and of the right of free inquiry and private judgment in all cases, and yet how far are we from these exalted privileges in fact! There exists, I believe, throughout the whole Christian world, a law which makes it blasphemy to deny or doubt the divine inspiration of all the books of the Old and New Testaments, from Genesis to Revelations. In most countries of Europe it is punished by fire at the stake, or the rack, or the wheel. In England itself it is punished by boring through the tongue with a poker. In America it is not better; even in our own Massachusetts, which I believe, upon the whole, is as temperate and moderate in religious zeal as most of the States, a law was made in the latter end of the last century, repealing the cruel punishments of the former laws, but substituting fine and imprisonment upon all those blasphemers upon any book of the Old Testament or New. Now, what free inquiry, when a writer must surely encounter the risk of fine or imprisonment for adducing any argument for investigating into the divine authority of those books? Who would run the risk of translating Dupuis? But I cannot enlarge upon this subject, though I have it much at heart. I think such laws a great embarrassment, great obstructions to the improvement of the human mind. Books that cannot bear examination, certainly ought not to be established as divine inspiration by penal laws. It is true, few persons appear desirous to put such laws in execution, and it is also true that some few persons are hardy enough to venture to depart from them. But as long as they continue in force as laws, the human mind must make an awkward and clumsy progress in its investigations. I wish they were repealed. The substance and essence of Christianity, as I understand it, is eternal and unchangeable, and will bear examination forever, but it has been mixed with extraneous ingredients, which I think will not bear examination, and they ought to be separated.

Context: As a path to the perception of a deeper, comprehensive reality, in which the experiencing individual is also sheltered, meditation, in its different forms, occupies a prominent place today. The essential difference between meditation and prayer in the usual sense, which is based upon the duality of creator-creation, is that meditation aspires to the abolishment of the I-you-barrier by a fusing of object and subject, of sender and receiver, of objective reality and self.
Objective reality, the world view produced by the spirit of scientific inquiry, is the myth of our time. It has replaced the ecclesiastical-Christian and mythical-Apollonian world view.
But this ever broadening factual knowledge, which constitutes objective reality, need not be a desecration. On the contrary, if it only advances deep enough, it inevitably leads to the inexplicable, primal ground of the universe: the wonder, the mystery of the divine — in the microcosm of the atom, in the macrocosm of the spiral nebula; in the seeds of plants, in the body and soul of people.
