Every person of learning is finally his own teacher; the reason of which is, that principles, being of a distinct quality to circumstances, cannot be impressed upon the memory; their place of mental residence is the understanding, and they are never so lasting as when they begin by conception.

Thus much for the introductory part.
From the time I was capable of conceiving an idea, and acting upon it by reflection, I either doubted the truth of the christian system, or thought it to be a strange affair; I scarcely knew which it was: but I well remember, when about seven or eight years of age, hearing a sermon read by a relation of mine, who was a great devotee of the church, upon the subject of what is called Redemption by the death of the Son of God.
After the sermon was ended, I went into the garden, and as I was going down the garden steps (for I perfectly recollect the spot) I revolted at the recollection of what I had heard, and thought to myself that it was making God Almighty act like a passionate man, that killed his son, when he could not revenge himself any other way; and as I was sure a man would be hanged that did such a thing, I could not see for what purpose they preached such sermons.

This was not one of those kind of thoughts that had any thing in it of childish levity; it was to me a serious reflection, arising from the idea I had that God was too good to do such an action, and also too almighty to be under any necessity of doing it.
I believe in the same manner to this moment; and I moreover believe, that any system of religion that has anything in it that shocks the mind of a child, cannot be a true system.
It seems as if parents of the christian profession were ashamed to tell their children any thing about the principles of their religion.

They sometimes instruct them in morals, and talk to them of the goodness of what they call Providence; for the Christian mythology has five deities: there is God the Father, God the Son, God the Holy Ghost, the God Providence, and the Goddess Nature.

But the christian story of God the Father putting his son to death, or employing people to do it, (for that is the plain language of the story,) cannot be told by a parent to a child; and to tell him that it was done to make mankind happier and better, is making the story still worse; as if mankind could be improved by the example of murder; and to tell him that all this is a mystery, is only making an excuse for the incredibility of it.
How different is this to the pure and simple profession of Deism! The true deist has but one Deity; and his religion consists in contemplating the power, wisdom, and benignity of the Deity in his works, and in endeavouring to imitate him in every thing moral, scientifical, and mechanical.
The religion that approaches the nearest of all others to true Deism, in the moral and benign part thereof, is that professed by the quakers: but they have contracted themselves too much by leaving the works of God out of their system.
