 In an attempt to defeat the Cartesian or Platonist and remind us that mental predicates have perfectly ordinary standards of application, Ryle focuses on what is observable. It is part of his war against what is not only occult (and observable only through introspection) but also against what is hidden from the viewpoint of a third-party observer. But, in focussing on what is observable, he does not commit himself to reducing what is observable itself to sequences of “muscular behaviour”. Those who attribute to Ryle a “soft” behaviourism are at least correct that the reminders he issues to ward off Cartesianism include frank appeal to what he later will describe as actions much higher up on the “sophistication ladder” like paying a bill, or scoring a goal, as well as to what he will later call “concrete”, “per se”, or “infra” doings like scribbling numbers on a cheque book or kicking a ball between two posts.
