...the nature of enthusiasm, that among the vast numbers of errors floating about in the universe, there are a few established truths — truths which no one...are equal to two right angles, and the square of the hypotenuse is equal to the squares of the other two sides. And you would almost be persuaded to conclude...

...power of at once enabling Zerah Colburn to perform his mental calculations, Pythagoras to prove that the square of the hypothenuse is equal to the squares of the other two sides of a right-angled triangle, and Laplace to write " La Mecanique Celeste." Observation has corrected...

...thinkers had framed out the atomic theory, and had, it is said, found the proof of the theorem that the square of the hypothenuse is equal to the squares of the other two sides of a right-angled triangle. In much later times the decimal system was perfected by some genius in...

...proceeds entirely from the undeterminate meaning of words, which is corrected by juster definitions. That the square of the hypothenuse is equal to the squares of the other two sides, cannot be known, let the terms be ever so exactly defined, without a train of reasoning and enquiry....
