<p>My husband got his BA in philosophy and M.Phil about 30 years ago. He is one of the best people I know at reasoning and researching solutions to problems of all kinds - household, health, technology, etc. - and that includes my engineer father. It taught him critical thinking and how to analyze an issue. Of course, he can only put an empty plastic bottle on the counter and not in the recycling container about 6" below it, but I can live with that.</p>
