My Philosophy as Way of Life (PWOL) series of essays has now being going on since July 2018, and has produced 388 articles and counting. Naturally, people have a tendency to focus on the latest entries, but — if I may be forgiven for saying so — some of the early ones are worth reading as well.

Marcus did become emperor in 161 CE, at the death of Antoninus, and he immediately appointed the far less capable Lucius as co-emperor (Lucius died in 169 CE, probably of the plague, leaving Marcus sole emperor). …

2, A first glimpse of the Meditations: Apparently, Marcus’ personal philosophical diary was known relatively soon after his death, as it is, for instance, mentioned by Themistius about two centuries after. But we have to…
