“Nowhere is freedom more important than where our ignorance is greatest—at the boundaries of knowledge, in other words, where nobody can predict what lies a step ahead. Though freedom has been threatened even there, it is still the field where we can count on most men rallying to its defense when they recognize the threat. If in this book we have been concerned mainly with freedom in other fields, it is because we so often forget today that intellectual freedom rests on a much wider foundation of freedom and cannot exist without it. But the ultimate aim of freedom is the enlargement of those capacities in which man surpasses his ancestors and to which each generation must endeavor to add its share—its share in the growth of knowledge and the gradual advance of moral and aesthetic beliefs, where no superior must be allowed to enforce one set of views of what is right or good and where only further experience can decide what should prevail.”
