.IntroductionSociology is described by Layder (2006, p.1) as “How everyday encounters and individual behavior influence and are influenced by the broader social environment in which we live » Bauman & May (2001. p.1) describe a visual image of the production of sociology as being a “collection of books in a library”. The discussion within this collection broadly follows major concepts and perspectives, with many authors as well as key peer-reviewed authors. I will first present the main concepts and the main perspectives of a selection of these authors, and will aim to conclude, that is to say the "sociological thinking" acquired by "unpacking" this knowledge, which can be applied to social work today. “Social theory consists of major authors, perspectives and key questions, there are many different strands which, although they present obstacles, can be brought together and connected in the study of sociological knowledge” Layder (2006 , preface). Specifically, I will look at section 5.1 of the Professional Skills Framework (2012) “being able to reflect on and consider the impact of inequality, disadvantage and discrimination on those who use social work” and I will focus on the application of sociological thinking in the fight against oppression. Practice.ConceptsSocial theory parallels philosophy in that, although sociology is a social science, the question of from what position do we form our concepts? exists. There are generally three points of view, called three dualisms in sociology. Giddens (2013, chapter 1) suggests that the most important questions facing theory are not potential obstacles and divisions in dualisms, but "how different aspects of social reality relate to each other ". of paper ......e theory and practice of social work, Palgrave Mcmillan.
