"For humans there is no wilderness more difficult to explore than the night -- not the seas, not the poles, not even the stars. What equipment can the explorer take along? The most powerful flashlight can only turn a small slice of night into day. Infrared scopes and special lenses are windows into the night, but windows imply walls. Darkness will not be remolded to human vision because it is a part of that vision. It is the vision that must be remolded."
