The journalist and the philosopher are both engaged in study. Journalists are trained to look at the world around them. They describe it, and they see its sins. And they become righteous.
Philosophers are trained to look at the world inside them, to forget their surroundings. They discover this world with fear and trembling. When they turn their gaze toward the world around them, they see in it the manifestation of their own sins. And they may become merciful.
A human being may wake up a philosopher and go to bed as journalist. Or vice versa. Or be journalist to some and philosophers to others. Perhaps the best combination is to be journalist to yourself and philosopher to others.
