Building the structure of ideas.

" Nature is the source of all true knowledge. She has her own logic, her own laws, she has no effect without cause nor invention without necessity. ”
- Leonardo da Vinci

“Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit.”
― Aristotle
