Radix, the Latin word for root, is the origin of the word radical. In contemporary political philosophy, the term describes activists who challenge established views and who operate outside the parameters of social convention to achieve political aims, sometimes employing extreme or violent methods in that pursuit.
The concept of political radicalism evolved out of the language and logic of the scientific revolution when educated intellectuals began to view the world in scientific, secular terms. It gained popularity during the Enlightenment as social theorists employed the new method of critical thinking to challenge traditional religious and political dogma.
TO RADICALIZE IS TO GET TO THE ROOT OF OR THE SOURCE OF THE PROBLEM, OF ONES OPPRESSION WHEN USED IN A MARXIST SENSE.
“To be radical is to go to the root of the matter. For man, however, the root is man himself.” ― Karl Marx
