I reply to him and all- because academics who don’t engage culture and society with responsible scholarship and who only care whether what they write is publishable in book form are
1- out of touch and behind the curve; and
2- driven more by economic considerations than a genuine desire to teach.
Teachers teach- that’s what they do. Scholars share their ideas- it’s not as if they can help it. Scholars don’t hunt and peck for ideas to write about but rather their real problem is narrowing down from the thousands of ideas they have the one which will occupy them in the present moment.
For those to whom sharing ideas, writing posts, thinking ‘out loud’, and pondering with a wider community those thoughts which drive and – in a sense – possess them, is a ‘waste of time’ I can only say ‘then the whole of your life would be better spent selling insurance or engaging in some telephone solicitation’ because scholars who don’t burn with passion for learning and teaching should serve the public in some other fashion or form than academics.
If telling others what you’ve learned or what you are presently learning is a waste of time, academics isn’t the field for you, and blogging is something you should avoid because you’ll seldom ever do it and when you do, you’ll only try to justify your own indolence.
Better to spend your time slamming back a six pack and watching strange sporting events or taking long walks along the beach or some such other sort of time wasting than posting posts which complain about your own lack of posting posts.
