Quite to the contrary, while you can build hierarchies in Smalltalk, they are nowhere near as important as they are in C++, Java, or C#. Smalltalk, (and derivative languages like Ruby and Python) are dynamically typed, and therefore don't rely on inheritance to give them dynamic polymorphism. Therefore building inheritance hierarchies is of much less importance in these languages.
