The French philosopher, mathematician, and physicist, René Descartes, is best known for his philosophical statement "I think, therefore I am".
So "blog away" and see what impact you can make and what you can learn as well.
Descartes argued that thought exists, but cannot be separated from the person. I think, therefore I know I exist.
The modern twist on this is: "I blog, therefore Iam". I blog so that others know I exist and can share my thoughts.
