Locke would concede full liberty to idolaters, by whom he means the
Indians of North America, and he makes some scathing remarks on the
ecclesiastical zeal which forced these “innocent pagans” to forsake

[103] their ancient religion. But his toleration, though it extends
beyond the Christian pale, is not complete. He excepts in the first
place Roman Catholics, not on account of their theological dogmas but
because they “teach that faith is not to be kept with heretics,” that
“kings excommunicated forfeit their crowns and kingdoms,” and because
they deliver themselves up to the protection and service of a foreign
prince—the Pope. In other words, they are politically dangerous. His
other exception is atheists. “Those are not all to be tolerated who deny
the being of God. Promises, covenants and oaths, which are the bonds of
human society, can have no hold upon an atheist. The taking away of God,
though but even in thought, dissolves all. Besides also, those that by
their atheism undermine and destroy all religion, can have no pretence
of religion to challenge the privilege of a Toleration.”

Thus Locke is not free from the prejudices of his time. These exceptions
contradict his own principle that “it is absurd that things should be
enjoined by laws which are not in men’s power to perform. And to believe
this or that to be true does not depend upon our will.” This applies to
Roman Catholics as to Protestants, to atheists as to deists. Locke,
however, perhaps thought

[104] that the speculative opinion of atheism, which was uncommon in his
day, does depend on the will. He would have excluded from his State his
great contemporary Spinoza.

But in spite of its limitations Locke’s Toleration is a work of the
