"If a Labour movement, on a bourgeois basis, has hitherto existed in the country where the new movement is awakening it will certainly not disappear all at once"

Karl Radek's quote is describing the emergence of a new labour movement in a nation where a labour motion already exists. He is suggesting that the existing labour motion, which is based on bourgeois concepts, will not all of a sudden vanish when the brand-new movement begins to take shape. Instead, he believes that the 2 motions will exist together and that the brand-new movement will slowly change the old one. This is due to the fact that the brand-new movement will be more progressive and will be much better able to fulfill the requirements of the working class. Radek's quote is a pointer that modification is a gradual process which it is important to be patient and understanding when it pertains to the development of a brand-new labour motion. It is also a suggestion that the existing labour motion should not be disregarded or forgotten, as it has the prospective to contribute to the success of the new motion.
