Is there a philosophical term for fear of the unknown, other than xenophobia?
If such a term doesn't exist, can you think of a philosopher who discussed the phenomenon?
I should probably define "unknown." I'm including things we simply have no knowledge of; for example, what lies beyond the borders of the universe? It could also include questions like what is death, or what's going to happen to me after I die?
The unknown could thus include things we are vaguely aware of but which we don't fully understand.
