I have discovered with advancing years that few things are entirely black or white, but more often different shades of grey.

we all suffer in our different ways from being prisoners of birth.

A work of art is worth what someone will pay for it.

And I did wonder - because it's now three years ago since I left prison - whether there would come a time when I would forget it, or it would be in the past as anything else might be - no, it's there every day of my life.

I was allowed to ring the bell for five minutes until everyone was in assembly. It was the beginning of power.

When I was deputy chairman I could travel from Glasgow to Edinburgh without leaving Tory land. In a two-week period I covered every constituency in which we had an MP. There were 14. Now we have only one. We appear to have given up.

But the thing I felt most strongly about, and put at the end of one of the prison diaries, was education.
