Ad nauseam is a Latin term for argument or other discussion that has continued to the point of nausea. … indicating that the topic has been discussed extensively and those involved have grown tired of it.
Repetition does not change the accuracy or value of a statement or argument.
People, aviation, the world is not absolute, thus by considering the in-between ‘grey’ area opens the possibility of identifying something to learn. It is up to us to take these possibilities, accept that there is always something new to learn.
Avoid ‘what is’, and consider ‘what might be’; accept that no single view is absolute, not applicable to all situations, particularly those which you did not attend.
