It's a quote from Federalist Paper 51

"If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions." - James Madison.

The OP purposely misspelled angels as angles, as in "90 degree right angles", something that a protractor would measure, but a ruler would be less useful with angles.

I liked it.
