Truism


A truism is a claim that is so obvious or self-evident as to be hardly worth mentioning, except as a reminder or as a rhetorical or literary device, and is the opposite of falsism.
In philosophy, a sentence which asserts incomplete truth conditions for a proposition may be regarded as a truism. An example of such a sentence would be "Under appropriate conditions, the sun rises." Without contextual supporta statement of what those appropriate conditions arethe sentence is true but incontestable.
Lapalissades, such as "If he were not dead, he would still be alive", are considered to be truisms.
