“The bourgeoisie cannot exist without constantly revolutionising the instruments of production,
and thereby the relations of production, and with them the whole relations of society.
Conservation of the old modes of production in unaltered form, was, on the contrary, the first
condition of existence for all earlier industrial classes. Constant revolutionising of production,
uninterrupted disturbance of all social conditions, everlasting uncertainty and agitation
distinguish the bourgeois epoch from all earlier ones.”
