"If our generation happens to be too weak to establish Socialism over the earth, we will hand the spotless banner down to our children. The struggle which is in the offing transcends by far the importance of individuals, factions and parties. It is the struggle for the future of all mankind. It will be severe, it will be lengthy. Whoever seeks physical comfort and spiritual calm let him step aside. In time of reaction it is more convenient to lean on the bureaucracy than on the truth. But all those for whom the word ‘Socialism’ is not a hollow sound but the content of their moral life - forward! Neither threats nor persecutions nor violations can stop us! Be it even over out bleaching bones the future will triumph! We will blaze the trail for it. It will conquer! Under all the severe blows of fate, I shall be happy as in the best days of my youth; because, my friends, the highest human happiness is not the exploitation of the present but the preparation of the future."

- Leon Trotsky, I Stake My Life
