Establishment as a vital matter. And I have generally remarked
that when clergymen of the Church profess extreme catholicity of
spirit, and declare that they do not regard it as a thing of the
least consequence whether a man be Churchman or Dissenter, intelligent
Nonconformists receive such protestations with much contempt, and
(possibly with injustice) suspect their utterer of hypocrisy. If
you really care much about any principle; and if you regard it as
of essential importance; you cannot help feeling a strong impulse
to intolerance of those who decidedly and actively differ from you.

Here are some further vulgar errors, primary and secondary:

Primary--Idleness, and excessive self-indulgence;

Secondary--Penances, and self-inflicted tortures.

Primary--Swallowing whole all that is said or done by one's party;

Secondary--Dread of quite agreeing, or quite disagreeing on any
point with any one; and trying to keep at exactly an equal distance
from each.

Primary--Following the fashion with indiscriminate ardour;

Secondary--Finding a merit in singularity, as such.

Primary--Being quite captivated with thought which is striking and
showy, but not sound;

Secondary--Concluding that whatever is sparkling must be unsound.
