Life is all a "quote". Long or short, clear or obscure, in language or in the vernacular, in alphabetic or ideographic form, every man has his own. The Net is full of them, true or false, trying to break through the wall of incommunicability. Call them quotes or aphorisms, proverbs or sayings, they are all carefully documented in this book. The author mentions the source, the provenance, without intervening, leaving the reader free to use them.

It is difficult to determine the most brilliant thoughts of all time, as the concept of "brilliance" is subjective and can vary greatly from person to person. Some people may consider a thought brilliant if it is original, innovative or revolutionary, while others may consider a thought brilliant if it is profound, inspiring or emotionally resonant.
There have been many brilliant thoughts throughout history, and it is not possible to list them all here. Some notable examples of brilliant thoughts might include:

"I think, therefore I am", a philosophical statement attributed to René Descartes which has become one of the most famous expressions of the concept of consciousness. “The only thing that is constant is change,” a quote attributed to the ancient Greek philosopher Heraclitus that has become a popular saying in modern times.

"All men are created equal," a phrase from the Declaration of Independence that has become a fundamental tenet of the United States and a central tenet of the civil rights movement. “The only thing we have to fear is fear itself,” a quote from President Franklin D. Roosevelt's inaugural address that has become one of the most famous statements in American political history.

“The unexamined life is not worth living,” a quote from the ancient Greek philosopher Socrates that has become a key tenet of philosophical inquiry. Again, these are just a few examples of brilliant thoughts, and there are many more that could be mentioned. Ultimately, what constitutes a brilliant thought is a matter of personal interpretation and can vary from person to person.… (altro)
