The Marx Communist Manifest

The Marx Communist Manifest  lays out the basic logic of his historical method which points to the inevitability of socialism. Why did Marx call his take on socialism “scientific”?

Drawing on the relevant material in Heywood, and on our class discussions, explain how the ideas of social democracy were developed as an alternative to the revolutionary violence that is part of Marx’s vision.  How is social democracy different from Marx’s socialism? Does it lead to eventual overthrow of capitalism by socialism; or does ultimately serve to strengthen capitalism itself?

Socialist ideas have enjoyed a resurgence of popularity of sorts here in the United States.  The DSA is up to over 1000,000 members.  Are the ideas of Marx and other socialist thinkers still relevant to the historical period that we are living in?  Why or why not?  Be sure to fully elaborate your points.
