The X-Files, Season 2

Mulder:
[voiceover] The conquest of fear lies in the moment of its acceptance. And understanding what scares us most is that which is most familiar, most common place... It's been said that the fear of the unknown is an irrational response to the excesses of the imagination. But our fear of the everyday, of the lurking stranger, and the sound of foot-falls on the stairs, the fear of violent death and the primitive impulse to survive, are as frightening as any X-file, as real as the acceptance that it could happen to you.
