Level of Certainty

How do you know that the next time you press on your automobile brakes, they will work? The truth of the matter is that the only way you can be absolutely certain that the breaks will stop the car is after they have actually done so. Anything less then this level of certainty leaves room that the breaks will not actually work when you need them. Yet not even able to be 100% certain, we will get that car up to speeds exceeding 75mph. How could we possibly make a decision like this? We do it all the time.

How do we know what we know? How do we understand certainty? In the seven-minute video below, I discuss this in greater detail.
