The association carried the following introductory note:

Two decades have passed since the publication of the work "Socialism Is a Science" on Nov. 1, 1994, but the validity of Kim Jong Il's lucid analysis of the faith in socialism as a science which runs through the work and the frustration of socialism in some countries at that time and the invincibility of Korean-style socialism is clearly proved still now.

In the work he clarified that the collapse of socialism in various countries does not mean the failure of socialism as a science but the bankruptcy of opportunism which made socialism degenerated. He indicated that socialism is undergoing temporary painful ups and downs due to opportunism but it is sure to be revived and win the final victory for its scientific accuracy and truth.

His definition of socialism was like a beacon indicating the way for the global socialist movement to clear the dark clouds hung over it and many revolutionaries of the world accepted his work as their faith and rose up to revive socialism.

His work dealt a heavy ideological blow at the imperialists and the renegades of socialism who gave up the class struggle by yielding to imperialists.

The revolutionary people of the world boldly have turned out in the struggle against the exploitation by capital, firmly convinced of the victory of socialism, their ideal.

It is our hope that the revolutionaries and progressive people all over the world will regard his work as a must book.
