Heideggefs Conception of Being-with （Mitsein） and His Simple Designation of Social and Political Reality in the Black Notebooks

Despite Heidegger insists that Being and Time cannot be read as a kind of existential philosophy, such interpretation still holds in some aspect, for in it, the main content is a special kind of phenomenology of life, even be called repeatedly as the foundation of the ontology of Being in general. The project of establishing an ontology of Being in general was ultimately never carried out. What Heidegger provides in Being and time is nothing but a phenomenology of life. It is peculiar that love and friendship as an important element of life is deliberately ignored. Such a deficiency of Heidegger, namely lacking love and friendship in fundamental ontology of Dasein, is probably the reason for his political fallacy during the II-World-War, notorious political mistake in his recent published Black Notebooks.

Theories of Social Media： Philosophical Foundations

Although many different views of social media coexist in the field of information systems （IS）, such the- ories are usually not introduced in a consistent framework based on philosophical foundations, This paper introduces the dimensions of lifeworld and consideration of others, The concept of lifeworld includes Descartes＇ rationality and Heidegger＇s historicity, and consideration of others is based on instru- mentalism and Heidegger＇s ＂being-with,＂ These philosophical foundations elaborate a framework where different archetypal theories applied to social media may he compared： Goffman＇s presentation of sell Bourdieu＇s social capital, Sartre＇s existential project, and Heidegger＇s ＂shared-world,＂ While Goffman has become a frequent reference in social media, the three other references are innovative in IS research, The concepts of these four theories of social media are compared with empirical findings in IS literature, While some of these concepts match the empirical findings, some other concepts have not yet been inves- tigated in the use of social media, suggesting future research directions,

Heidegger,Communal Being,and Politics

There are two critical,but opposite interpretations of Heidegger's understanding of being as a social ontology.One charges Heidegger with adhering to an anti-social"private irony,"while the other charges him with promoting a"self-canceling"totality.The current essay replies to these two charges with a discussion of Heidegger's understanding of being as"communal being,"which is implicated both in the early Heidegger's concept of"being-in-the-world-with-others"and in the later Heidegger's keyword of Ereignis.It argues that Heidegger's understanding of being as communal being is neither identical with totalitizing publicness nor the same as voluntaristic egotism.According to Heidegger,both the publicness of das Mem and voluntaristic egotism are the real threats to humanity at present.Because of them,we human beings are in danger of being uprooted from the earth upon which we-as communal beings-have already and always dwelled and lived with others from the very beginning of human history.
