Yes, I know: Sowell was on this blog only ten weeks ago but in the mean time he has celebrated his 90th birthday. I think that’s worth marking.

But I have to admit that there’s also a far more prosaic reason for today’s posting. My computer is in hospital. If they can’t fix it, I’ll replace it. Meanwhile I am hobbling along on a tablet.

To post one of my speech critiques, I need a screenful of many windows and tabs from which I lift references, precise timings, URLs for hyperlinks, etc. It goes against the grain to have a week without a blog post, but robbed of my normal work environment I feel I just want to put a video here, and let it speak for itself. I cannot think of anyone better to do that than Dr Thomas Sowell.

By way of introduction I offer you a comment published below this video on YouTube –

As a black man I just want to say … this man changed my life and taught me how to think. I’ve never felt so free.
