“A fateful thing has been happening. The East is waking up from its slumber. The wisdom of Hinduism, Buddhism, Taoism and Confucianism is becoming available to the world. Already, it is having a transforming effect on the minds of the people, particularly in countries where there is freedom to seek and express. Dogmas are under a cloud; claims on behalf of Last Prophethood and Only Sonship, hitherto enforced through great intellectual conditioning, brow-beating, and the big stick, are becoming unacceptable. Religions of proxy are in retreat. More and more men and women now seek authentic experience. Borrowed creed will not do. Men and women are ceasing to be obedient believers and are becoming seekers. They no longer want to be anybody’s sheep, now that they know they can be their own shepherds. An external authority, even when it is called God in certain scriptures, threatening and promising alternately, is increasingly making less and less impression; people now realize that Godhead is their own true, secret status and they seek it in the depth of their own being. All this is in keeping with the wisdom of the East.”

Context: At least at a basic “thin” morality level, some commonalities exist between Asia and the West. In addition, as many have pointed out, whatever the degree to which they divided humankind, the world’s major religions — Western Christianity, Orthodoxy, Hinduism, Buddhism, Islam, Confucianism, Taoism, Judaism — also share key values in common. If humans are ever to develop a universal civilization, it will emerge gradually through the exploration and expansion of these commonalities. Thus, in addition to the abstention rule and the joint mediation rule, the third rule for peace in a multicivilizational world is the commonalities rule: peoples in all civilizations should search for and attempt to expand the values, institutions, and practices they have in common with peoples of other civilizations.
This effort would contribute not only to limiting the clash of civilizations but also to strengthening Civilization in the singular (hereafter capitalized for clarity). The singular Civilization presumably refers to a complex mix of higher levels of morality, religion, learning, art, philosophy, technology, material well-being, and probably other things. These obviously do not necessarily vary together. Yet scholars easily identify highpoints and lowpoints in the level of Civilization in the histories of civilizations. … When civilizations first emerge, their people are usually vigorous, dynamic, brutal, mobile, and expansionist. They are relatively uncivilized. As the civilization evolves it becomes more settled and develops the techniques and skills that make it more Civilized. As the competition among its constituent elements tapers off and a universal state emerges, the civilization reaches its highest level of Civilization, its “golden age,” with a flowering of morality, art, literature, philosophy, technology, and martial, economic, and political competence. As it goes into decay as a civilization, its level of Civilization also declines until it disappears under the onslaught of a different surging civilization with a lower level of Civilization.

So also in ancient Greece, in ancient Rome, in the whole ancient world, all over Asia and Europe.

Source: What's So Great About Christianity
Context: Today courts wrongly interpret separation of church and state to mean that religion has no place in the public arena, or that morality derived from religion should not be permitted to shape our laws. Somehow freedom for religious expression has become freedom from religious expression. Secularists want to empty the public square of religion and religious-based morality so they can monopolize the shared space of society with their own views.

Original: (zh-CN) 一切矛盾着的东西，互相联系着，不但在一定条件之下共处于一个统一体中，而且在一定条件之下互相转化，这就是矛盾的同一性的全部意义。列宁所谓“怎样成为同一的（怎样变成同一的），——在怎样的条件之下它们互相转化，成为同一的”，就是这个意思。
