Imagination is a very high sort of seeing, which does not come by study, but by the intellect being where and what it sees, by sharing the path, or circuits of things through forms, and so making them translucid to others.
When forced to work within a strict framework, the imagination is taxed to its utmost and will produce its richest ideas. Given total freedom, the work is likely to sprawl.
Opinion involves belief (for without belief in what we opine we cannot have an opinion), and in the brutes though we often find imagination we never find belief.
People read a lot of stories about witches, fairies, paranormals, and children possessed by evil spirits. They go to films showing rituals featuring pentagrams, swords, and invocations. That's fine, people need to give free reign to their imagination and to go through certain stages. Anyone who gets through those stages without being deceived will eventually get in touch with the Tradition.
Rather than pointing fingers or assigning blame, let’s use this occasion to expand our moral imaginations, to listen to each other more carefully, to sharpen our instincts for empathy and remind ourselves of all the ways that our hopes and dreams are bound together.
