On opinions…
How do you know whether or not my point of view completely full of shit?
After all everyone is different and opinions are like assholes.
There is a test.
Before you can be reasonably convinced that you are right about a particular idea, you should be sure that you understand the objections and positions of your most articulate antagonists.
You should find out whether your views are supported by sound knowledge of opposing ideas or by your misconceptions of opposing ideas.
You make this distinction by seeing whether or not you can state the objections and positions of your opponents to their satisfaction.
Even if you can successfully do this, you cannot be absolutely certain of being right about your own ideas, but the probability of being right is considerably higher if you pass this test.
As you attempt to articulate the ideas of your antagonists, be prepared to change your mind, to discover evidence contrary to your ideas – evidence that may alter your views.
Intellectual growth often occurs this way.
