penalized for heterodoxy, in some and perhaps in
most of these cases heterodoxy was only a pretext. They do not
invalidate the general facts that the advance of knowledge was not
impeded by prejudice, or science retarded by the weight of unscientific
authority. The educated Greeks were tolerant because they were friends
of reason and did not set up any authority to overrule reason. Opinions
were not imposed except by argument; you were not expected to receive
some "kingdom of heaven" like a little child, or to prostrate your
intellect before an authority claiming to be infallible.

But this liberty was not the result of a conscious policy or deliberate
conviction, and therefore it was precarious. The problems

[51] of freedom of thought, religious liberty, toleration, had not been
forced upon society and were never seriously considered. When
Christianity confronted the Roman government, no one saw that in the
treatment of a small, obscure, and, to pagan thinkers, uninteresting or
repugnant sect, a principle of the deepest social importance was
involved. A long experience of the theory and practice of persecution
was required to base securely the theory of freedom of thought. The
lurid policy of coercion which the Christian Church adopted, and its
consequences, would at last compel reason to wrestle with the problem
and discover the justification of intellectual liberty. The spirit of
the Greeks and Romans, alive in their works, would, after a long period
of obscuration, again enlighten the world and aid in re-establishing the
reign of reason, which they had carelessly enjoyed without assuring its
foundations.

on "Socrates" in the Encyclopoedia Britannica, last edition.

[2] He stated the theological difficulty as to the origin of evil in
this form: God either wishes to abolish evil and cannot, or can and will
not, or neither can nor will, or both can and will. The first three are
unthinkable, if he is a God worthy of the name; therefore the last
alternative must be true. Why then does evil exist? The inference is
that there is no God, in the sense of a governor of the world.

Tyrrell's Lectures on Latin Poetry.
