There is nothing worse than being ashamed of parsimony or poverty.
If time is money, it seems moral to save time, above all one's own, and such parsimony is excused by consideration for others. One is straight-forward.
Scientists often talk of parsimony (as in "the simplest explanation is probably correct," also known as Occam's razor), but we should not get seduced by the apparent elegance of argument from parsimony; this line of reasoning has failed in the past at least as many times as it has succeeded.
Mere parsimony is not economy. Expense, and great expense, may be an essential part in true economy.
The mentally disturbed do not employ the Principle of Scientific Parsimony: the most simple theory to explain a given set of facts. They shoot for the baroque.
A parsimony of words prodigal of sense.
