“William James wrote (in Principles of Psychology in 1890): "In youth we may have an absolutely new experience, subjective or objective, every hour of the day. Apprehension is vivid, retentiveness strong, and our recollections of that time, like those of a time spent in rapid and interesting travel, are of something intricate, multitudinous and long-drawn-out. But as each passing year converts some of this experience into automatic routine which we hardly note at all, the days and the weeks smooth themselves out in recollection to contentless units..." Life seems to speed up as we get older because life gets less memorable as we get older.”

“Life seems to speed up as we get older because life gets less memorable as we get older.”

“Our life is made up of time; our days are measured in hours, our pay measured by those hours, our knowledge is measured by years. We grab a few quick minutes in our busy day to have a coffee break. We rush back to our desks, we watch the clock, we live by appointments. And yet your time eventually runs out and you wonder in your heart of hearts if those seconds, minutes, hours, days, weeks, months, years and decades were being spent the best way they possibly could. In other words, if you could change anything, would you?”

“But the most valuable lesson he taught me was this: Every day we get older, and some of us get wiser, but there's no end to our evolution. We are all a mess of contradictions; some of our traits work for us, some against us.”

“There is new research showing that our creative potential increases with age. Our creativity is a product of our inner and outer experience, and as we get older, we have all kinds of experience to draw on. Also, research tells us that creativity brings energy, vitality and good health.”

“When men have realized that time has upset many fighting faiths, they may come to believe... that the ultimate good desired is better reached by free trade in ideas-- that the best test of truth is the power of the thought to get itself accepted in the competition of the market, and that truth is the only ground upon which their wishes safely can be carried out. That at any rate is the theory of our Constitution. It is an experiment. As all life is an experiment. Every year if not every day we wager our salvation upon some prophecy based upon imperfect knowledge. ”
