These are the most stable links in the data. Ranked by similarity. Filter with `corpus` (a corpus name or `bible`). Scores come from the nine world religions texts and the World English Bible. For each text, a paragraph's best match becomes a percentile within that text, after an adjustment for paragraph length. The texts are not independent votes: a paragraph that sounds devotional tends to score well in all of them. These are measures of closeness in meaning by an embedding model, not claims about the teachings. ## OpenAPI ````yaml GET /scriptures/insights/pairs openapi: 3.1.0 info: title: Urantia Papers API version: 1.0.0 description: >- A developer and AI-agent friendly API for the Urantia Papers.

The Cynic. Although the Cynics traced their philosophy to Diogenes of Athens, they derived much of their doctrine from the remnants of the teachings of Machiventa Melchizedek. Cynicism had formerly been more of a religion than a philosophy. At least the Cynics made their religio-philosophy democratic. In the fields and in the market places they continually preached their doctrine that “man could save himself if he would.” They preached simplicity and virtue and urged men to meet death fearlessly. These wandering Cynic preachers did much to prepare the spiritually hungry populace for the later Christian missionaries. Their plan of popular preaching was much after the pattern, and in accordance with the style, of Paul’s Epistles. corpus: id: diogenes-laertius-6-hicks-1925 slug: diogenes-laertius-6 religion: Cynicism title: 'Lives of Eminent Philosophers, Book 6: The Cynics' translator: R.

But we will go on to append the doctrines which they held in common – if, that is, we decide that Cynicism is really a philosophy, and not, as some maintain, just a way of life. They are content then, like Ariston of Chios, to do away with the subjects of Logic and Physics and to devote their whole attention to Ethics. And what some assert of Socrates, Diocles records of Diogenes, representing him as saying: "We must inquire into Whate'er of good or ill within our halls is wrought." They also dispense with the ordinary subjects of instruction. At least Antisthenes used to say that those who had attained discretion had better not study literature, lest they should be perverted by alien influences. similarity: 0.679463 similaritySmall: 0.720913 - paragraph: id: 4:122.2.3 standardReferenceId: '122:2.3' paperId: '122' paperTitle: Birth and Infancy of Jesus sectionTitle: Gabriel Appears to Elizabeth text: >- “While your husband, Zacharias, stands before the altar in Jerusalem, and while the assembled people pray for the coming of a deliverer, I, Gabriel, have come to announce that you will shortly bear a son who shall be the forerunner of this divine teacher, and you shall call your son John.
