2.2 The picture has the logical form of representation in common with what it pictures.
 
Adulterously in love with Ottoline Morrell and weary of intellectual work, Russell grooms Wittgenstein as his successor in the five year philosophy lectureship he holds at Trinity College. When Hermine Wittgenstein visits Cambridge in 1912, Russell tells her: "We expect the next big step in philosophy to be taken by your brother."

But Russell worries that Wittgenstein is pushing himself too hard. Always questioning, arguing, wrestling with the invisible shape of thought.

Russell writes a paper titled The Essence of Religion, and Wittgenstein storms protesting into his rooms. Russell: "He felt I had been a traitor to the gospel of exactness; also, that such things are too intimate for print."

Wittgenstein seems on the verge of a nervous breakdown. Russell: "He suddenly stood still and explained that the way we had spent the afternoon was so vile that we ought not to live, or at least he ought not, that nothing is tolerable except producing great works or enjoying those of others, that he has accomplished nothing and never will - all this with a force that knocks one down."

Or: "He seems not far removed from suicide, feeling himself a miserable creature, full of sin."
