This essay offers an explanation of how assertions express that the speaker has a propositional attitude toward what's asserted. The explanation is that this feature of assertion is owed to a hearer's spontaneous mindreading. I call this the assertoric mindreading hypothesis. Once developed and defended, the hypothesis is used to investigate which attitude is expressed. Since the attitude expressed is the attitude tracked during mindreading, the attitude must have a certain profile. It is argued that only factive attitudes like knowledge have this profile. Non‐factive attitudes like belief or acceptance are ineligible.

  自信的读心术

本文解释了断言如何表达说话者对所断言的内容具有命题态度。解释是，这种断言的特征是由于听者自发的读心术。我称之为断言读心假说。一旦提出并捍卫了这个假设，这个假设就被用来研究表达了哪种态度。既然所表达的态度是读心术时跟踪的态度，那么这种态度必须具有一定的特征。有人认为，只有像知识这样的事实态度才具有这种特征。像信念或接受这样的非事实态度是没有资格的。
