Peter and Thomas in their book have described and link their theories and the so-called symbolic interaction to American sociology. It is a very symbolic link since it has started as a promising point for the analysis of the ordinary universal sense of human knowledge. Both Peter and Luckmann were determined to show the fact gets socially constructed which merely means that the objective of the feature of the world have retained a shape they have which is as a result of the social actions. The other meaning is that the element of the object can be understood through another scheme that is conceptual as well as incommensurable and irrefutable. One of the most enduring contributions which are being made is the one that is get created through a social process as well as relations which iteratively produced by many social as well as individuals actions (Berger, 1981).Apparently, from the beginning, the authors have a conception of knowledge which was not standardized. It is the certainty that phenomena are in real life situation whereby they possess specific features. The definition of this term has more to do the degree of subjective confidence in which an individual has. Additionally, the topic knowledge whether it is sociologically or philosophical is an exciting aspect if it sheds light on the cognitive entities that needed to be arrived to as well as formulating the representations of the universe around them. In this book, the authors have tried to explain the sociology of knowledge theory by describing how the society maintains and creating the reality. The process requires being done both on societal as well as individual level (Berger, 1991).The reality in its definition means a particular phenomenon which we can recognize by having our own independent volition. Knowledge indicates the certainties of the aspects are real and they have a specific character. Knowledge gets passed as well as accumulated on the understanding of what reality is by the society. To be able to make an analysis of our daily life the book has suggested phenomenological study which has tried to present the new observation of consciousness. The paper describes the continuation of social interactions which varies every day as we move forward each day from here to there. In the book, the importance of knowledge is emphasized in a very significant manner. Language has become a repository for accumulating experiences and meaning vast. The observation made shows that style has its origin as well as its references from the daily life. The bridges observed in the languages and different zones of reality that integrates into a significant, temporal and social variation. Therefore, we can say that social fact is a construction that is constructed by the society which consists of people who work at different levels (Pfadenhauer, 2017).However, despite the fact that individuals make institution it does not give a full definition of what social construction means. My overall assessment then implies an argument that is offered by Luckmann which I think will be negative. Instead, they are presenting an interpretation of a process of socialization whereby biology is even finished. The book has discussed a little about solving mental problem representation as well as it lacks assay on social cognition. It has been considering a recurring theme all the alternative social realities which require a lot of understanding that need to be understood relating to humankind of stuff and norms. It is a reality that there are things in the society that are inevitable about the specific interactions and codes in our community.ReferencesBerger, P. L., & Luckmann, T. (1991).
