Descartes Discourse Part 2

Descartes compares the learning of new ideas to the foundations of a building. He says that it is better to build new ideas on a new foundation, rather then building upon the same old ideas and foundations. Just as one would not continue to build on an old building, but he/she would build on a new foundation. This idea of a foundation ties into the "seek the truth for yourself and not accept only others ideas" idea that he had. I like this metaphor that he has used because it gives a very clear picture of how one should seek their own truths and study their own ideas to themselves and not just live off of what they have learned from others, or the old foundations.
