Why do ideas from classic works get transformed in later works?

When introducing literature to a new class I ask two questions: "Why do we study it and what can we learn from it?" Now, if you're a teacher you'll know that it's not always a smooth ride to the final destination, which is all part of the fun, but the answer we usually get to, albeit with teacher sat-nav switched on, is that through literature, we can visit cultures impossible for us to experience ourselves. From our reading, we can begin to understand what it must have been like to live in a particular time, under certain conditions, in different parts of the world. But the best bit is that we can do all this while honing those oh-so-necessary and desired critical-thinking skills.
