as one which could not prudently be avowed to the world. This lesson of keeping my thoughts to myself, at that early age, was attended with some moral disadvantages; though my limited intercourse with strangers, especially such as were likely to speak to me on religion, prevented me from being placed in the alternative of avowal or hypocrisy. I remember two occasions in my boyhood, on which I felt myself in this alternative, and in both cases I avowed my disbelief and defended it. My opponents were boys, considerably older than myself: one of them I certainly staggered at the time, but the subject was never renewed between us: the other who was surprised and somewhat shocked, did his best to convince me for some time, without effect.
The great advance in liberty of discussion, which is one of the most important differences between the present time and that of my childhood, has greatly altered the moralities of this question; and I think that few men of my father’s intellect and public spirit, holding with such intensity of moral conviction as he did, unpopular opinions on religion, or on any other of the great subjects of thought, would now either practise or inculcate the withholding of them from the world, unless in the cases, becoming fewer every day, in which frankness on these subjects would either risk the loss of means of subsistence, or would amount to exclusion from some sphere of usefulness
