Seth Godin recently asked on his blog a question I used to pose to my daughter when she was in high school, “How much of what we want, really want, is due to the ideas that culture has given us, and how much is truly what we need?”
It was easy for me to observe her and ask if she, for example, hated cafeteria food at school because the food was bland or tasted bad or if she was just saying what “everyone” was saying.
It is less easy for us to observe ourselves and ask if we believe something because we’ve thought it through or because “everyone” is saying it on social media.
There is probably a reason that even the most ancient wisdom literature teaches that unsubstantiated opinion is the lowest form of thought. Forming an opinion from a combination of learning and experience reflected on is a much higher form. Even better when we are open to someone pointing out the possibility of misinterpreting a source or a thought we may have overlooked.
