Though he maintained throughout his life a sympathy towards religious values and beliefs, he acknowledged that his philosophy had been marked by a reaction towards what he saw as his own father's too narrow an outlook.

Dear Pamela,As a Brit, it’s nice to see someone from ‘over the pond’ who’s got most of the information about Afternoon Tea correct for a change: I now live in Vinci, Italy (yes where Leonardo was born), and now offer afternoon tea to Italians in our home dining would take you to task on one item in your article,(there’s always a critic!) and that is about Cream Tea in which you say: “Cream Tea — A simple tea service consisting of scones, clotted cream, marmalade or lemon curd and tea.” Cream Tea traditionally consists of scones served with clotted cream and strawberry said that if people prefer to have their scones (and it’s pronounced ‘skons’ as far as I’m concerned),with an alternative, I have no problem with that, it’s a free world (supposedly)!For example I sometimes fill my Victoria Sponge with lemon curd instead of the traditional raspberry jam and fresh raspberries both of which balance well with a nice cup of sweet Luck with the book!
