There are at least three reasons as to why reading Lacan is still very important today, in the 21st century, year 2021. The first reason is that whether you like it or not, Lacan is one of the most important 20th century French thinkers – not only psychoanalysts, but thinkers. So one reason for reading Lacan is that his ideas have been exceptionally influential. It would be a mistake to ignore someone’s work that has been so influential and that has had such an impact on such a broad range of fields.
The second reason for reading Lacan is that, over the years, Lacan has received quite a bit of bad press, much like Freud. So whenever you read Lacan, you know that you’re reading someone whose work is controversial – someone who didn’t shy away from courting controversy and from being polemical, and whose work, even within psychoanalysis, is still very much considered to be controversial.
That in itself makes it much more interesting to read someone, because you know that there is something in that person’s ideas that is not going to be bland. You know that somewhere the controversy is going to come across as a radical, transformative, innovative experience that could effectively change your way of thinking, which then brings me quite nicely to the third reason for reading Lacan.
