Therefore the most essential preliminary condition necessary for an attack on such a difficult stage of the human road is that the authorities should succeed in convincing the masses that the immediate objective which is now being fought for is the only one that deserves to be considered and the only one on which everything depends. The broad masses are never able clearly to see the whole stretch of the road lying in front of them without becoming tired and thus losing faith in their ability to complete the task. To a certain extent they will keep the objective in mind, but they are only able to survey the whole road in small stages, as in the case of the traveller who knows where his journey is going to end but who masters the endless stretch far better by attacking it in degrees. Only in this way can he keep up his determination to reach the final objective.
