What is Enlightenment? Immanuel Kant

I agree with many others when saying that this reading was difficult, but most of Kant's readings are difficult to understand. You have to take the time to read and re-read most of his passages. After going over the packet in class, I began to understand and deeply think about what some of the main points of this passage were. I was assigned to read and write about the passage that says,
          "An age cannot bind itself and ordain to put the succeeding one into such a condition that it cannot      extend its knowledge, purify itself of errors, and progress in general enlightenment."
What I think this passage means is that every era or age should be able to experience and decipher things for themselves. The age before them cannot set anything for sure because each person needs to be able to develop their own methods or knowledge, and be able to make its own errors in order to be enlightened.
