A little web search gave the following at

"Pluralitas non est ponenda sine neccesitate" 
"Frustra fit per plura quod potest fieri per pauciora" 
"Entia non sunt multiplicanda praeter necessitatem" 

The principle states that "Entities should not be multiplied
unnecessarily." Sometimes it is quoted in one of its original Latin
forms to give it an air of authenticity.
