Can Economics or Linguistics Be Scientific?

Natural sciences are ‘scientific,’ meaning that they delve into the (ontologically objective) material reality, the existence of which is independent of human will. The social sciences can never be scientific in the same sense, because their field of research is the (always ontologically subjective) social reality that is generated by humans and fully dependent on human will. Ergo, economics cannot be a science, because human views and decisions on the exchange of goods change unpredictably, that is, how and when human groups concerned want. In the case of linguistics, this discipline can be scientific at the level of probing into language as the biological capacity for speech. As such it is a product of biological evolution and part of the (ontologically objective) material reality. However, when dealing with Einzelsprachen (or languages, as actualizations of the biological capacity for speech, actualizations produced and maintained by human groups), the linguist cannot hope to achieve scientific exactness or discover scientific in its character laws, because Einzelsprachen are part of the social reality. It is humans and their groups alone who decide on how Einzelsprachen are shaped. As such Einzelsprachen are (ontologically subjective, imagined) actualizations of the (ontologically objective, material, biological) capacity for speech, that is, language.
