Add the squash and sauté, stirring, until the squash softens, about 10 minutes. Season with salt and pepper. Add the stock and marjoram, heat to boiling, cover, reduce heat, and boil gently for 30 minutes. Add the artichoke purée and mix well. Pour the soup into a food processor and process into a coarse purée. Serve the soup in warm bowls with freshly grated Parmesan cheese to garnish.
