"Witold Doroszewski treated the culture of language as a significant part of linguistics. He believed that popularising correct Polish and knowledge of language is more important than pointing out and analysing linguistic errors since promoting positive models is the basis of work on language. He defined language as one of the forms of the human activity in the society. Apart from numerous specific solutions, radio advice, collected in 3 volumes of O kulturę słowa (About the culture of the word), he also formulated several general principles of the culture of language. He presented the first set of criteria for linguistic correctness, developed theoretical assumptions of the dictionary of correct Polish, defined the notion of linguistic norm and linguistic error. Many findings and observations contained in his studies have been valid to date, his way of treating prescriptive linguistics has been continued by his students."
