Within the last week, I heard that expression above.
From whom, we will not go into now.
It translates as "My sword (is) my pen."
The very previous post wherein I wrote that in intelligent beings it is the differences that join us together is a prime example. The differences are proof of Intelligence. Our disagreements are proof of our common humanity.
I attack (my sword!) the old ways of thinking with my writing (my pen!)
I wish I understood all this a bit more... to make me feel at ease.
I don't know... maybe I should mention that the phrase is in Arabic?
