Sine II

The Latin word sine is the source of the following cognate words:

in French  sans  without  eg  sans argent  penniless

in Italian  senza  without  eg  senza carni  without meat

in Spanish  sin  without  eg  sin gas  without gas


& surprisingly in English  sans  without.

William Shakespeare used the word sans in his All the world's a stage monologue:

... Last scene of all,
That ends this strange eventful history,
Is second childishness and mere oblivion,
Sans teeth, sans eyes, sans taste, sans everything.

Sine

The preposition sine means without.  Sine governs the ablative.  eg

sine invidia  without envy
sine ira  without anger
sine mora  without delay
sine pecunia  without money

sine dubio  without doubt
sine loco et anno  without the place and year

sine prole  without offspring

sine ictu  without a blow

sine die  without a day
sine spe  without hope, without expectation

Sine qua non literally means without which not.  If something is sine qua non it is necessary.

Lex Parsimoniae

Lex Parsimoniae is more commonly known in English as Occam's Razor (also spelt Ockham's Razor), after the medieval philosopher William of Ockham who made great use of this methodological principle.There are several Latin formulations of Occam's Razor including:

Entia non sunt multiplicanda praeter necessitatem. (Entities must not be multiplied beyond necessity.)

Pluralitas non est ponenda sine necessitate. (Plurality should not be posited without necessity.)

Frustra fit per plura quod potest fieri per pauciora. (It is futile to do with more things that which can be done with fewer.)

Numquam ponenda est pluralitas sine necessitate (Plurality must never be posited without necessity.)
