acular, in alphabetic or ideographic form, every man has his own.

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.

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.
