Sorry, but when I hear about De Gaulle & Adenauer or Mitterand & Kohl forming personal bonds and that being a boon to democracy and freedon, I immediatly think of Trump, Putin, Xi or Kim forming personal bonds. It's not the personal bonds but the ideas of the bodning people.

Am I the only one who dislikes the literary genre of using dialogues in philosophical writing? It began with Platon and went downhill from there.

I'm surprised to learn from Radick's 'Disputed Inheritance' that Mendel's laws are not simply taught, in Britain, as the uniformity of hybrids from pure breeds (1. law), the 3:1 ratio in the F2 generation (2. law) etc. Never heard of the 1. law as referring to gene pairs (alleles) etc. #hps #evobio
