The opportunism of the flâneur is great in life and business—but not in personal life and matters that involve others. The opposite of opportunism in human relations is loyalty, a noble sentiment—but one that needs to be invested in the right places, that is, in human relations and moral commitments. The error of thinking you know exactly where you are going and assuming that you know today what your preferences will be tomorrow has an associated one.

Nassim Taleb

“No amount of experimentation can ever prove me right; a single experiment can prove me wrong.”

“Art, like life, should be free, since they are both experimental.”

“And you find gold, so to speak, effortlessly, just as in rational but undirected trial-and-error-based research. It is exactly like options, trial and error, not getting stuck, bifurcating when necessary but keeping a sense of broad freedom and opportunism.Trial and error is freedom.”

George Santayana

William Blake
