Biologie zbavená břemene teleologie

The use of teleological language in biology is burdened with many difficulties. Speakers in everyday and scientific discourse confuse functions with purposes and misunderstand functionality, finality, and intentionality. The paper is structured into three sections. In the first part the difference between Platonic supranatural and Aristotelian quasi-natural account of teleology will be explained, with examples from the history of philosophy of biology. The second part will present the Darwinian approach to etiology that constitutes a more sound alternative to the teleological explanation. In the last section I will briefly introduce the teleological bias that is studied by developmental and cognitive psychologists. I believe that this psychological inclination is the real source of intuitive worldviews that are incompatible with contemporary science.
