Unlike the rationalism of the French Revolution, true liberalism has no quarrel with religion, and I can only deplore the militant and essentially illiberal antireligionism which animated so much of nineteenth-century Continental liberalism. … What distinguishes the liberal from the conservative here is that, however profound his own spiritual beliefs, he will never regard himself as entitled to impose them on others and that for him the spiritual and the temporal are different sphere which ought not to be confused.
