Union of civilizations, joining of cultures, and conjugation of religions are the universal concerns of the cosmic man. Eight existing civilizations of the world are not enough for the ever-changing taste of man who is in favor of varieties. Therefore, new human civilizations need to be born and developed and they surely will.

The theory of Union of Civilizations can be discussed along with the theory of The Clash of Civilizations by Huntington or the idea of Dialogue Among Civilizations. This theory concerns the future of civilizations and the solutions to the cultural and religious problems of the world today, and considers this union the foundation of a universal comprehensive civilization. Due to this theory, the selfishness of the governments is destructive; on the other hand, avoiding the separation of cultures and focusing on globalization and universality are emphasized. In this proposal, the way to achieve this globalization and universality is not the clash or negotiation of different civilizations, but their unification as well as their cultural and religious interaction.

This union and connection has been started centuries before the theory of Clash of Civilizations, or Dialogue Among Civilizations. Today, there exists no single civilizations except for the ones which are about to extinct or join the legends.

The great civilizations have to join together and result in new civilizations. The current civilizations will be cast away and they finally die like the disabled aged while they pave the way for the fresh newly born replacements. Similarly, the descendants of these new civilizations will do their best to fill the gap between the internal and external heritages and rescue the long forgotten spirituality; they will bring the past into the future.

Union of civilizations of the East and the West is a good example of the mentioned fact; this union has brought a new civilization into the world which is distinct from its original resources. It is a tangible example of distinction of the antique and appearance of the novel.

An amalgamation of cultures is taking place. I see it as proof that something is happening, something is being born, that we are in a phase when one age is succeeding another, when everything is possible. Yes, everything is possible, because our civilization does not have its own unified style, its own spirit, its own aesthetic.

Civilizations are the generations of the racial soul. As family-rearing, and then writing, bound the generations together, handing down the lore of the dying to the young, so print and commerce and a thousand ways of communication may bind the civilizations together, and preserve for future cultures all that is of value for them in our own. Let us, before we die, gather up our heritage, and offer it to our children.

It is the destiny of our race to become united into one great body, thoroughly connected in all its parts, and possessed of similar culture. Nature, and even the passions and vices of Man, have from the beginning tended towards this end. A great part of the way towards it is already passed, and we may surely calculate that it will in time be reached.

Our ability to reach unity in diversity will be the beauty and the test of our civilisation.

We have to all come together and create unity out of diversity that the destiny that [we ]build will be one that is right not just for now but for generations to come.

Today's world calls for new attitudes, new ways of life - more responsible, aware, and egalitarian. We need more communion and more dialogue. By affecting us regardless of political, territorial, racial, ethnic and religious boundaries, climate change unites the world through shared suffering. In order to fight it, we need to keep united and to transform this union into an action that is collective, global, and shared, involving all strata of society all around the world.

There is richness in unity. For instance, the European countries have united but because the bond they have between them is not a bond of faith, because it is not a bond of love, they are not successful. When the Islamic world unites, the bond they have between them will be a bond of love and there will be no borders, no visas, no passports and thus both trade and friendship will easily be established and sustained. There will be a sound, vivid, lively life based on love and generosity, far removed from selfishness and egoism.

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.

Today we must secure not a clash between civilizations, but a reconciliation and bringing together of the values of Islam and Christianity.
