How did philosophers spread knowledge

They told the knowledge to other people who spread the information throughout the world. Back then there weren't computers or phones, so people had to go on horseback, walk, or maybe even a ship. Nowadays, we can just write emails and text messages and just call! We take technology for granted.

The  pan-african movement  was an "emotional, cultural, psychological and ideological  movement  that began among the  african  dispora in the western hemisphere, for a closer  purpose, so that  african  people could feel secure, attain political, economic as well as psychological power visa vis other races or world regions" .
