 Information and communication technology (simply referred to as ‘information technology’ here) is changing many aspects of human endeavour and existence. This is beyond dispute for most. What are contested are the social and ethical implications of these changes. Possible sources of these disputes are the multiple ways in which one can conceptualize and interpret the information technology/society interrelationship. Each of these ways of conceptualization and interpretation enables one to see the information technology/society relationship differently and therefore construe its social and ethical implications in a different manner. At the center of this technology/society interrelationship we find many complex questions about the nature of the human, the technical, agency, autonomy, freedom and much more. This is indeed a vast intellectual landscape, which can obviously not be explored here in its fullness. This entry is about just one particular perspective on this landscape. It is primarily concerned with the phenomenological approach to interpreting information technology and its social and ethical implications. It should be noted from the start that there is not a unified phenomenological tradition or approach to information technology in particular, or other phenomena more generally. The phenomenological tradition consists of many different approaches that share certain characteristics (certain family resemblances, one might say) but not all. We may however suggest, with Don Ihde (2003,133), that they all accept that “phenomenology investigates the conditions of what makes things appear as such [as that which we take them to be].” Differently stated, phenomenology suggests that there is a co-constitutive relationship between us and the phenomena we encounter in our engagement with the world. In this sense phenomenologists would suggest that to understand the technology/society relationship we need to reveal how they co-constitute each other—i.e. draw on each other for their ongoing meaning and sense. We will elaborate more precisely what this means in  section 2  below. However, in order to understand the distinctiveness of the phenomenological approach other possible ways of interpreting this technology/society relationship will also be outlined briefly below.
