"Multiplicity ought not to be posited
without necessity." ie. Everything should be as simple as possible,
but not simpler. - Occam's Razor
William of
Ockham 1285 - 1349
"It is unwise to pay too much... but
it is worse to pay too little. When you pay too much...
you lose a little money...that is all. Flowmeter price.
When you pay too little... you
sometimes lose everything... because the thing you
bought, was incapable of doing the thing
it was bought to do.
The common law of business balance
prohibits paying a little and getting a lot...it
cannot be done.
If you deal with the lowest bidder,
it is well to add something for the risk you
run... and, if you do that, you will have enough
to pay for something better."
John Ruskin 1819 - 1900
