Logic and dialectic are like two different ways to think and learn.
Logic is a way of understanding the world by looking at facts and making conclusions from them. It's like figuring out a puzzle. You use facts and evidence to make your arguments.
Dialectic is a way of learning by discussing things with someone else and finding out how two different points of view can come together to create a new understanding. It's like debating something out with a friend. You both offer different ideas and over time you come to a conclusion of what is true.
