Many things I know because I have proof that my knowledge is right – I gain the knowledge of a bread recipe, and by baking that bread to completion and eating a delicious result, I know I now have that knowledge.
Other things I know because I’ve seen others do the opposite, and I don’t desire having the same result. I was in the car with my mum when she hit a deer, which crumpled up the front end of the car spectacularly. I’ve learned to slow down when driving in deer territory. Well, that or hit them with less damage to the car – we had deer sausages to last us a good while, and cheaper than you can buy in the store after the insurance deductible was paid.
Sometimes what I think I know is proven incorrect, but this allows me to then become knowledgeable about the issue. Similarly, sometimes I know that I don’t know, so I go and find the knowledge and thus learn.
Living is learning, and learning is living.
