The philosophical programme of Tadeusz Kotarbiński has been called somewher (by himself) a small one. He wanted to renounce dealing with traditional ontological or epismotological problems and confine himself to preparing the linguistic tools appropriate to philosiophy. This goal was not so small but rather maximalistic and demanding for his pupils. He wanted to have a homogeneous rational linguistic structure universally appropriate for raising all scientific problems. As Kotarbiń disciples we should be able to translating every not vanishing philosophical problem into reistic language.
