Meeting Jacques Lacan

I was introducced to the works of Jacques Lacan a few days back. Lacan is a French psychoanalyst who made significant contributions to the field of psychoanalysis after Sigmund Freud. He started off the 'return to Freud' movement where he reemphasized the importance of Freud's concepts discussed under dreams, slips of the tongue and jokes revealing more about a person than he intends to. Freud talked about how the unconscious slips into our consciousness at our most unguarded moments like the ones mentioned above.
Lacan introduced the concepts of the imaginary, the symbolic and the real. His concepts evolved right through his life, so it is very difficult to come to a single definitive statement regarding those. He introduces the unconscious as a language. He talks about how a baby first becomes aware of itself when it sees its image in the mirror and later when it learns language.
He also talks about the Theory of Dialectics where there is unity in opposites and everything exists only with its very negation (popularly understood today as the yin yang concept). He introduces the concept of how the self is nothing but the lack of the other, and that we are all aware of the self only when we know the other. He talks about oedipal complex and how nature and culture go hand in hand. That the primal desire for incest, is suppressed by laws and by society adn this forms the very basis our being.
The real for him, is that which cannot be symbolized. Something which is there even before we know it, and which cannot be expressed or suppressed. The real is that which is non existent, or atleast cannot be explained.
The concepts are fascinating, but extremely confusing and difficult to follow. These are very few of the basic concepts that I could make sense of. Still reading...
