Love is the great intangible. ... Frantic and serene, vigilant and calm, wrung-out and fortified, explosive and sedate -- love commands a vast army of moods.

Everyone admits that love is wonderful and necessary, yet no one can agree on what it is.

Smell is the mute sense, the one without words.

We ogle plants and animals up close on television, the Internet and in the movies. We may not worship the animals we see, but we still regard them as necessary physical and spiritual companions. Technological nature can't completely satisfy that yearning.
