“The mutation of bacteria and viruses are merely hereditary fluctuations around a median position; a swing to the right, a swing to the left, but no final evolutionary effect.”

“I swing as hard as I can, and I try to swing right through the ball.”

Babe Ruth (1895–1948) American baseball player

As quoted in Go for the Gold: Thoughts on Achieving Your Personal Best (2001) by Ariel Books
Context: I swing as hard as I can, and I try to swing right through the ball. In boxing, your fist usually stops when you hit a man, but its possible to hit so hard that your fist doesn't stop. I try to follow through in the same way. The harder you grip the bat, the more you can swing it through the ball, and the farther the ball will go. I swing big, with everything I've got. I hit big or I miss big. I like to live as big as I can.

“Look, here is the way I swing. I swing hard. I don’t punch the ball. I have bat control, and I don’t go for home runs, but I still swing as hard as some fellows who swing for the fences. My back is practically to first base when I finish the swing. I have to turn around before I can start running. Sometimes the ball is in the fielder’s hands before I drop the bat.”

Roberto Clemente (1934–1972) Puerto Rican baseball player

“The hardest thing to do is to swing quietly, with control and restraint. Lots of bands swing loudly. I refuse to let my band play loudly in order to try to swing when it isn’t swinging softly. I think that the best jazz in the long run is the jazz that is controlled and will swing on its own terms.”

John Dankworth (1927–2010) British musician

“Financial markets are supposed to swing like a pendulum: They may fluctuate wildly in response to exogenous shocks, but eventually they are supposed to come to rest at an equilibrium point and that point is supposed to be the same irrespective of the interim fluctuations. Instead, as I told Congress, financial markets behaved more like a wrecking ball, swinging from country to country and knocking over the weaker ones.
It is difficult to escape the conclusion that the international financial system itself constituted the main ingredient in the meltdown process.”
