Durkheim is making a profound point here. He is saying that the pursuit of knowledge is made easier if there is a shared membership, which is what religion provides. So Thomas Aquinas in his Summa Theologica raises questions that could not be addressed in a university today, because there is a Safe Space provided by the faith. And, in a way, that is what too many students today are whining on about – they can cope with knowledge only if they are given membership first, and membership comes through closing your mind around items of dogma. But they have no dogma! All they have is the sense that some people have power and that they are not among them (a belief which is false in both parts).
