LENIN ON ORGANIZATION
XIII.
“A LETTER TO A GERMAN COMRADE.”
(Extract—Written August 14, 1921.)
. The resolutions on tactics and organization
 adopted at the Third Congress of the Communist
 International marks in my opinion, a great step
forward by the movement. Every effort must be
made to carry these two resolutions into effect. It
is difficult, but it can be done, and must be done.
Communists had first to declare their principles
to the world. That was done at the First Congress.
That was the first step.
The second step was to give the Communist International
 organizational form and to work out the
conditions for adoption into the International—
which were in fact the conditions for isolating ourselves
 from the centrists and the direct and indirect
agents of the bourgeoisie within the labor movement.
 That was effected at the Second Congress.
At the Third Congress we had to begin real positive
 work, and, in view of the practical experience
already gained in the struggle by the Communists,
to define concretely, how exactly the work was to be
carried on, from the point of view both of tactics
and organization. This third step was also made.
