Existentialism has been updated for the internet age. How do you know whether I really exist? Simple. I instant message, therefore I am, or in this case, IM.
The message is further reinforced with the iconic, smiley emoticon that is often inserted in instant messages, sometimes overused.
So if you are a student of philosophy and your professor asks how do you know if you exist, just wear this shirt to class. Just don't expect to pass with that answer. :)
This t-shirt is available in several different styles, colours and sizes by American Apparel, known for its quality and sweatshop-free, working environment. This design is also available on organic cotton which is grown without using harmful chemicals or pesticides.
