1、That statement is a tautology.

2、Generalized quasi-tautology of Gdel interval-valued logic system

3、To say that something is' adequate enough 'is a tautology.

4、to say that something is `adequate enough' is a tautology.

5、Algebraic structure of the disturbing fuzzy propositional logic and the properties of its generalized tautology;

6、To "prove the theorem" means to show that the implication is a tautology.

7、That is no tautology. Why can't there be things only discoverable by non-scientific means, or not discoverable at all?

8、The book Zhuang Zi shows the trinity of fable, randomness and tautology, which is different from the signified of conceptual thinking but is the signifier with implied meanings.

9、Firstly, on the basis of implication, originating from the limited Disturbing Fuzzy Propositional logic, discusses its logic algebra and the properties of its generalized tautology.

10、The whole of this objection is but another expression of the tautology: that there can no longer be any wage-labour when there is no longer any capital.

11、Using these algorithms, we can use computer mechanically to list truth value table of a group of propositional formulae, determine that if a given propositional formula is a tautology, a contradiction, or if the formula is satisfiable.

12、[《没有约束的现代*》，p42]这种论调背后的套套逻辑（tautology）是这样的：据说灵知主义者有体系；黑格尔有一个体系，所以黑格尔是灵知主义者，不止如此，所有的体系构建这都是灵知主义者。
