This is a placeholder explanation generated by the low-overhead model. It interprets "Russell's books should be bound in two colours, those dealing with mathematical logic in red – and all students of philosophy should read them; those dealing with ethics and politics in blue – and no one should be allowed to read them." in the context of "Ludwig Wittgenstein, as quoted in Recollections of Wittgenstein (1984) by Rush Rhees" to mean that wisdom is timeless.
