We must constantly question, examine, and search for answers to the so-called unknown riddles of existence. Whether you are religious, scientific, philosophical, or whatever, the fact remains that if you wish to understand anything, you must question assumptions of things. If someone defines something, and you simply accept it, or dismiss it, without questioning it, that is by definition ignorance. However, if you question and seek out the things that you don't understand, or that don't seem logical, then you are beginning to form a more constructive mind for yourself in the future.
