Morality without religion is only a kind of dead reckoning - an endeavor to find our place on a cloudy sea by measuring the distance we have run, but without any observation of the heavenly bodies.
Henry Wadsworth Longfellow

Much of my work in this period was concerned with exploring the logic of economic models, but also with attempting to reconcile the models with every day observation.
Joseph Stiglitz

My mother moved abroad when I was 11, my dad wasn't around from the time that I was a baby, so I was not the product of a family, but a product of observation - of watching what went on around me, of watching who I liked, what I didn't like, what I thought was good behavior and what I thought was bad behavior and tailoring myself accordingly.
Mark Strong

Gary Gygax

One hour of life, crowded to the full with glorious action, and filled with noble risks, is worth whole years of those mean observances of paltry decorum, in which men steal through existence, like sluggish waters through a marsh, without either honor or observation.
Walter Scott

One man's observation is another man's closed book or flight of fancy.
Willard Van Orman Quine

Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.
Denis Diderot

People's minds are changed through observation and not through argument.
Will Rogers

Poets, we know, are terribly sensitive people, and in my observation one of the things they are most sensitive about is money.
