Why Do We Love Quotations?

I love quotations, not all quotations, but the good useful ones.  I add them to the bottom of my emails as part of the signature file.  Here's one:

"Speak now, kiss now / Before the river freezes altogether."  - Troy Jollimore

If I read that all winter, it reminds me to speak and kiss.  Climate change might stop the river from freezing altogether, but there are still rivers of passion coursing within me.  I wouldn't want them to freeze, so I keep speaking and kissing.  Or this one:

"In the depth of winter, I finally learned that there was in me an invincible summer."  - Albert Camus

That one reminds me to be resilient.  You can tell from those quotes that I live in the north.

A lot of people also add quotations to their email.  We copy one another's.  My friend Sergio in Salvador, Brazil, translates quotations into Portuguese and copies them to the bottom of his email.  They look like this:

"A coragem é resistência ao medo, domínio do medo - não ausência do medo."
"Courage is resistance to fear, mastery of fear - not absence of fear."  - Mark Twain

Quotations are both reminders for me and little messages to others.  They nod to the great writers and thinkers of past and present.  Lines from speeches, songs, and conversations are pulled out of context.  Lyrics are extracted from songs to sing to the immediate moment:

"You live your life as if it's real, a thousand kisses deep."  - Leonard Cohen

William Renauld wrote me that he loved my sig file quotations because "the quotes stretch a particular experience into a common, shared space."  Yes, they do that - move all readers towards a moment of communal thoughtfulness.  Here's one of my favourite quotations:

"We are all here for a single purpose:  to grow in wisdom and to learn to love better.  We can do this through losing as well as through winning, by having and by not having, by succeeding or by failing.  All we need to do is to show up openhearted for class" - Rachel Naomi Remen

It's my birthday Thursday.  Please send me a question or a quotation.  I will use them in my speech.
