By 1811, he had sorted them into nearly 50 different types, with titles like “Attack us, you attack Government,” the “No precedent argument,” and the “Good in theory, bad in practice” fallacy. (One thing on which both Immanuel Kant and Bentham agree is that this last example is a fallacy: If something is bad in practice, there must be a flaw in the theory.)
边沁搜集各种谬误例证，它们常常来自议会辩论。1811年，他总结了50种不同类型的谬误，冠以《攻击我们就是攻击政府》、《没有先例的论点》、《理论漂亮，实践糟糕》的等标题。（一件康德和边沁都同意的事情是最后一个例子是一个谬误：某物如果在实践上很糟糕，那么在理论上必然也有缺陷。）
