As good as it gets

We have been to some excellent local concerts over the last few months which I haven’t mentioned here (from the likes of Igor Levitt, Rachel Podger and the English Concert, Cuarteto Casals, and a particularly on-form Academy of Ancient Music … Continue reading

David Makinson’s Sets, Logic and Maths

As I go through chapters of my Introduction to Formal Logic, heavily rewriting them for the second edition (only scattered paragraphs are surviving unaltered from the first edition, and I’m adding wholy new chapters too), I’m occasionally pulling other introductory books … Continue reading

Dennett: losing the plot

I’ve tried to read Daniel Dennett’s From Bacteria to Bach and Back. But I’ve lost the plot, and given up quite early in the book. I seem to now find Dennett’s penchant for metaphors, claims that are “sorta” true, analogies, free-wheeling speculation, his having-his-cake-and-eating-it … Continue reading

Setting tableaux using prooftrees.sty

[Updated] The first edition of IFL was typeset using FrameMaker (long since defunct on a Mac), so I’m having to LaTeX the second edition from scratch. I’m using Clea Rees’s fairly new package prooftrees.sty for downward-branching tableaux, a.k.a. truth-trees, since this seems … Continue reading
