The book entitled “Paradigmatic Fundamentals of Quantitative and Qualitative Research Methods in Human Sciences” provides the students and researchers interested in studies on the field of human sciences with an accurate and deep view to the logical foundations of scientific research and the controversies over the quantitative and qualitative research approaches. The students of humanities seek to answer the following questions: How is an empirical research linked to philosophical and paradigmatic foundations and a specific worldview? How are human sciences linked to natural sciences? What are the science paradigms? Is it possible to present a comprehensive definition for science? What role do the important elements in science paradigms play in the process of scientific research? How can a researcher enter the social world of human beings? In doing so, how does the researcher essentially presuppose man as the actor or creator of this world? With answering these questions and the other resulting questions, the book systematically provides the readers with a comprehensive theoretical and practical view of scientific research processes in quantitative and qualitative research approaches.
