Context: It is not in a person's nature to desire what he already has. Desire is a tendency, the start of a movement toward something, toward a point from which one is absent. If, at the very outset, this movement doubles back on itself toward its point of departure, a person turns round and round like a squirrel in a cage or a prisoner in a condemned cell. Constant turning soon produces revulsion. All workers, especially though not exclusively those who work under inhumane conditions, are easily the victims of revulsion, exhaustion and disgust and the strongest are often the worst affected.

Context: No one really starts anything new, Mrs Nemur. Everyone builds on other men's failures. There is nothing really original in science. What each man contributes to the sum of knowledge is what counts.

Context: I look upon ourselves as partners in all of this, and that each of us contributes and does what he can do best. And so I see not a top rung and a bottom rung — I see all this horizontally — and I see this as part of a matrix. And I see every human being as having a purpose, a destiny, if you like. And what my hope is that we can find some way to fulfill the biological potential, if you like — the destiny that exists in each of us — and find ways and means to provide such opportunities for everyone. Now at the moment the world is suffering from large numbers of people who have no purpose in life — for whom there is no opportunity — and that's sad.
