Punctuated Equilibrium
"Part of why you're so special, John, is that you're an extraordinary example of punctuated equilibrium*," Sherlock murmured in John's ear.
"Yes?" John managed to gasp through rough, desperate pants. His face showed his struggle, his fight to cling to the meaning of the words rather than be carried off by the wave of sensations now threatening to overwhelm him.
"Definitely," said Sherlock. He too felt himself succumbing. His control over his body was stronger than his lover's, but still, he didn't have long. For John, he pressed on.
"Ordinary people live their lives taking small timid steps, while you, my love, glide along with quiet grace, disguised as one of them. Then you jump…fearless…from Barts to Afghanistan…from sharing my flat…to sharing my bed. Evolution."
"I prefer to call it…taking…a leap…of faith… you know…like…like…Kierkegaard**." John moaned out his words. His body rocked and shuddered.
"You know…I don't like being compared…to a deity. My powers…such as they are…are derived…from logic…not magic." Unable to hang on any longer, Sherlock let go. "Oh, John!"
"Oh god!" was John's reply.
Sherlock smiled and took John's hand. "Better?"
"Brilliant, wonderful, but still over too fast. I honestly don't know whether talking helps."
"But, was it a good leap?"
John sighed happily. "I reached the stars, Sherlock, and they were blazing."
*Punctuated Equilibrium: Theory of evolutionary biology presented by Steven Jay Gould and Niles Eldredge in 1972 stating that species are generally stable, changing little for millions of years, but that this equilibrium is punctuated by a rapid burst of change (leaps) that results in a new species.
**Kierkegaard: 19th Century Danish Christian philosopher who argued that God's existence can only be known through a leap of faith as reason is inadequate.
