Better to admit it if you don’t know than to pretend that you do. And better to pretend you know some things than that you know everything. If you do the latter, that’s being a “know-it-all.” A dangerous approach to take to life. I like science because the true scientist admits to what he (she) doesn’t know.
Admission: I don’t know who won the Super Bowl. I don’t know if America can avoid an extreme right takeover–but I think we can. I don’t know if my new book will sell. I don’t know how to solve some relationship problems. I don’t know the ultimate fate of universe, but I believe that life and consciousness will survive in some form. And I believe that a universal spirit underlies it all. I don’t know how to deal with anger, at least some of the time. I don’t know the first thing about how to fix a car engine. Etc. Etc.
