和形而上学的宇宙观相反，唯物辩证法的宇宙观主张从事物的内部、从一事物对他事物的关系去研究事物的发展，即把事物的发展看做是事物内部的必然的自己的运动，而每一事物的运动都和它的周围其它事物互相联系着和互相影响着。事物发展的根本原因，不是在事物的外部而是在事物的内部，在于事物内部的矛盾性。任何事物内部都有这种矛盾性，因此引起了事物的运动和发展。事物内部的这种矛盾性是事物发展的根本原因，一事物和他事物的互相联系和互相影响则是事物发展的第二位的原因。这样，唯物辩证法就有力地反对了形而上学的机械唯物论和庸俗进化论的外因论或被动论。这是清楚的，单纯的外部原因只能引起事物的机械的运动，即范围的大小，数量的增减，不能说明事物何以有性质上的千差万别及其互相变化。

According to materialist dialectics, changes in nature are due chiefly to the development of the internal contradictions in nature. Changes in society are due chiefly to the development of the internal contradictions in society, that is, the contradiction between the productive forces and the relations of production, the contradiction between classes and the contradiction between the old and the new; it is the development of these contradictions that pushes society forward and gives the impetus for the supersession of the old society by the new. Does materialist dialectics exclude external causes? Not at all. It holds that external causes are the condition of change and internal causes are the basis of change, and that external causes become operative through internal causes. In a suitable temperature an egg changes into a chicken, but no temperature can change a stone into a chicken, because each has a different basis. There is constant interaction between the peoples of different countries. In the era of capitalism, and especially in the era of imperialism and proletarian revolution, the interaction and mutual impact of different countries in the political, economic and cultural spheres are extremely great. The October Socialist Revolution ushered in a new epoch in world history as well as in Russian history. It exerted influence on internal changes in the other countries in the world and, similarly and in a particularly profound way, on internal changes in China. These changes, however, were effected through the inner laws of development of these countries, China included. In battle, one army is victorious and the other is defeated, both the victory and the defeat are determined by internal causes.

In any revolution, its internal causes are fundamental and its external ones are supplementary.

It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be ... This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.

Categories of understanding along with everything else alter as societies change.

Thus three factors mark the transition from the old to the new society: a universal state as the final stage of the old society; a church developed in the old society and in turn developing the new; and the chaotic intrusion of a barbarian heroic age. Of these factors, the second is the most, and the third the least, significant.

The world today is experiencing a profound and rapid socio-cultural transformation. But the changes do not occur at a uniform pace, and the discrepancies in the change process have differentiated the various countries and regions of our planet.

The social and political order in some particular countries did change in the past, and it can change in the future as well. But this is exclusively a matter for the peoples themselves and of their choice. Any interference in internal affairs, any attempts to limit the sovereignty of states — whether of friends and allies or anybody else — are inadmissible.

One of the most interesting today is what is happening in China... It is watched with extreme interest by Hierarchy, and could still go in many directions, well, or not so well. The changes which have taken place have had traumatic, chaotic effects in China, for example, the great Cultural Revolution. The kind of changes that I am envisaging, which will take place in the five centres at first, will take place without these traumatic effects; in the normal democratic way, by logical legislation and general agreement. All sections of society will take part, which will ensure the adoption of the various changes, whereas in China, and Russia, many of them were imposed. In America and Britain, today, many social changes are opposed by finance rather than by decree, but the result is the same.

We have an external and an internal crisis situation facing us in our community. The external crisis is racism and colonialism, which works to systematically oppress us and is responsible for whatever internal crisis there is. The internal crisis is the result of an environment where drugs and violence (both social and physical) are rampant, and life is sometimes considered cheap. Black-on-Black crimes and internal violence are destroying our community. It is undoubtedly self-hatred and the desperate economic and social conditions we live under which makes us prey on each other. Drugs, frustrated rage, prostitution and other vices are symptoms of oppression.

Значение внешних и внутренних перемен, которые порою совершаются в нашей жизни, не всегда сразу нам ясно. Мы потрясены, испуганы - а потом как будто возвращаемся к прежнему существованию, но перемена уже совершилась. Никогда и нигде мы уже не будем прежними.

Two fundamental factors are at the base of this transformation. The first is the destruction of those religious, political, and social beliefs in which all the elements of our civilisation are rooted. The second is the creation of entirely new conditions of existence and thought as the result of modern scientific and industrial discoveries.
