"You need a vanguard organization in order to overcome the dangerous potential brought about by the uneven development of class militancy and class consciousness"

This quote by Ernest Mandel is referring to the requirement for a lead company in order to avoid the possible risk of an irregular development of class militancy and class consciousness. By this, Mandel is recommending that a vanguard company is essential to guarantee that the advancement of class militancy and class awareness is balanced and not lopsided. This is very important due to the fact that an irregular development of class militancy and class consciousness can lead to hazardous effects, such as class dispute and social unrest. Therefore, a vanguard organization is needed to guarantee that the advancement of class militancy and class awareness is even and balanced, and that the prospective danger of an irregular advancement is prevented.
