We regard as 'scientific' a method based on deep analysis of facts, theories, and views, presupposing unprejudiced, unfearing open discussion and conclusions. The complexity and diversity of all the phenomena of modern life, the great possibilities and dangers linked with the scientific-technical revolution and with a number of social tendencies demand precisely such an approach, as has been acknowledged in a number of official statements.

Nothing threatens freedom of the personality and the meaning of life like war, poverty, terror. But there are also indirect and only slightly more remote dangers. One of these is the stupefaction of man (the "gray mass," to use the cynical term of bourgeois prognosticators) by mass culture with its intentional or commercially motivated lowering of intellectual level and content, with its stress on entertainment or utilitarianism, and with its carefully protective censorship.

Our country, like every modern state, needs profound democratic reforms. It needs political and ideological pluralism, a mixed economy and protection of human rights and the opening up of society.

Intellectual freedom is the only guarantee of a scientific - democratic approach to politics, economic development, and culture.
