About William B. Irvine
You are obviously a thoughtful person. There is an excellent chance, though, that your thinking can be improved.
For one thing, you are likely capable of thinking more than you do. You are, in particular, capable of thinking about more things, and thinking about them more carefully than is presently the case.
It is also likely that your critical-thinking ability can be improved. Even if your reasoning skills are highly developed, they can be undermined by your emotions, as well as by the cognitive biases that are wired into your brain.
