The first thing that comes to our minds when we say ‘ghosts’ is the supernatural; it belongs to another realm, the unexplained realm, and remains a mystery, one that is constantly colliding with the world of science, the perennially explained realm. But, we think, there is more.  This issue we look at what it means to be invisible, to be ghost-like, to be confined to a space behind the curtain and still exist. We look at artistes who truly engage with the word and understand its connotations in real life – in how, often, our reactions to the unknown become the opportunity for morality, philosophy and science to intermingle; in how we carry the ghosts of our memories; in how we create the ghosts of society; and how, even through the use of language words and the arts, the ghosts of silence remain.
