To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

熟人

熟悉某种事物（在这里所讨论的“熟悉”的哲学意义上）就是直接意识到它。在整个西方哲学史上都讨论过我们熟悉某些事物的想法，但是在20世纪初期，分析哲学家特别关注了这一点，这些哲学家从贝特朗·罗素（Bertrand Russell）关于相识的著作中汲取了灵感。从那时起，许多哲学家，尤其是那些致力于自我知识或感知的哲学家，都使用熟人概念来解释有关人类经验和知识的各种事实。在本文中，我对这项工作进行了概述，特别关注了当代分析哲学中有关熟人的兴起文学。在更全面地说明了相识是（或应该是）之后，
