" Typically we learn to “argue” by assertion. That is, we tend to start with our conclusions—our desires or opinions—without a whole lot to back them up.

Marshaling our reasons, proportioning our conclusions to the actual evidence, considering objections, and all the rest—these are acquired skills. We have to grow up a little. "
