Matter and Meaning in the Digital Age
We inhabit two worlds – the world of matter and the world meaning (Halliday, 2005). I investigate these two worlds and the physical, biological, social and semiotic systems which connect them, using concepts from social semiotic theory (Halliday, 1978; van Leeuwen, 2005). In the first instance, humans receive information about the physical world through senses (for example, sight, hearing, touch, taste, and smell). However, sensory input from the environment is perceived and conditioned by social factors and influences, which include the context, culture, beliefs and values, and life experiences. These social systems are enacted, maintained, and changed through semiotic systems, conceived as systems of meaning. Following Halliday (2005), semiotic systems constitute a new order of complexity, because they involve physical systems (the material sign itself), biological systems (humans), social systems (society and culture) and meaning itself. In this talk, I discuss this last dimension; the world of meaning and its significance, with a focus on the digital age. I discuss how semiotic resources structure thought and reality and examine the changes which have taken place in the semiotic landscape through digital technology (O’Halloran, 2014). In doing so, I conceptualise the digital age as a one-way mirror and discuss the implications for the future.
