And if all this be termed vaunting, the objector may, perhaps, be placated by the repeated avowal that neither is rationalism proclaimed to be a wholly new way for the nations, nor is the rationalist as such acclaimed as the monopolist of good. He respectfully urges upon the best and ablest followers of other flags that under his they will not deteriorate or be less cherished; that their gifts are precious in his eyes; that he wants their collaboration for humanity's sake. His panegyric of Reason is but the praise of what is wisest and best in man: his 'ism' is the concern to put off dead husks of opinion, to lift all life to the plane of light. The religionist may, if he must, come over with permission to call the cultus of truth and sanity a religion: some there are who suppose themselves to solve the dispute by that means, as Spencer thought to solve it by inviting Science and Religion to join hands in an avowal of a common ignorance. Such eirenicons do not seem widely acceptable: it is really better to let words keep their historic meanings than wilfully to change their values. But if the question be whether rationalism is a creed to live by, an ideal to live by, let these pages be taken as giving part of the answer. Printed by T. and A.
