The assertion fallacy ... is the fallacy of confusing the conditions for the performance of the speech act of assertion with the analysis of the meaning of particular words occurring in certain assertions.

P. 141John Searle
The general nature of the speech act fallacy can be stated as follows, using “good” as our example. Calling something good is characteristically praising or commending or recommending it, etc. But it is a fallacy to infer from this that the meaning of “good” is explained by saying it is used to perform the act of commendation.
John Searle
There are two insults which no human being will endure: The assertion that he hasn't a sense of humor, and the doubly impertinent assertion that he has never known trouble.
Sinclair Lewis
From what can "ought" be derived. The most compelling answer is this: ethics must be somehow based on an appreciation of human nature - on a sense of what a human being is or might be, and on what a human being might want to have or want to be. If that is naturalism, then naturalism is no fallacy. No one could seriously deny that ethics is responsive to such facts about human nature. We may just disagree about where to look for the most compelling facts about human nature -n novels, in religious texts, in psychological experiments, in biological or anthropological investigations. The fallacy is not naturalism but, rather, any simple-minded attempt to rush from facts to values. In other words, the fallacy is greedy reductionism of values to facts, rather than reductionism considered more circumspectly, as the attempt to unify our world-view so that out ethical principles don't clash irrationally with the way the world is.
Daniel C. Dennett
I believe it is an established maxim in morals that he who makes an assertion without knowing whether it is true or false, is guilty of falsehood; and the accidental truth of the assertion, does not justify or excuse him.
Abraham Lincoln
Apartheid was based on a fallacy: the fallacy that nonwhites could be used as labor to drive society; that nonwhites could physically form a majority inside South Africa, but that they could not determine the nature of South African society.
