Many men and women use the square to perform their work, but honestly do they really understand the true meaning of the symbol they use. The following ia a little incite to this symbol.
The Square, as we are taught, and as we all well know, is an instrument having an angle of ninety degrees – exactly ninety degrees, not “about” ninety degrees, for no approximations are allowable in this instrument of precision.
That which is not square is crooked, and that which is not honest is dishonest, for we cannot place our reliance upon a partially-honest man. The value of this basic instrument, the square, lies in its accuracy, and the value of our standard of honesty depends wholly upon uncompromising strictness in maintaining it.
