Vacuous truth
A vacuous truth is a statement that asserts that all members of the empty set have a certain property. For example, the statement "all cell phones in the room are turned off" may be true simply because there are no cell phones in the room. In this case, the statement "all cell phones in the room are turned on" would also be vacuously true, as would the conjunction of the two: "all cell phones in the room are turned on and turned off".

באופן ריק

במתמטיקה, נהוג לומר על טענה כי היא נכונה באופן ריק אם נכונותה אינה עומדת כלל למבחן, משום שהיא עוסקת באובייקטים שאינם קיימים. לדוגמה, "כל מספר ראשוני המתחלק ב-6 מסתיים בספרה 9" - הטענה נכונה, מכיוון שאין ראשוניים שמתחלקים ב-6.
