In writing and reading you must learn before you can teach. Yet more so in life.
'You were born a slave: you have no voice.'
'And the heart within me laughed.'
'They will pour scorn on virtue and sting with their abuse.'
In these five chapters, Marcus writes a couple of thoughts along with some quotes from previous Stoics.
The first one is a thought about Socrates. It is a bit cryptic, but seems to allude that Socrates felt no embarrassment about his natural state.
In the second one, the idea is to learn to walk before you run; to learn to read and write before teaching others. Therefore, one should learn to live (learn philosophy) before actually living.
In chapter 30, a reminder that we are all slaves.
In chapter 31, another cryptic one - perhaps a laugh at all the vain ambitions of others; and being content with knowing the Truth.
In chapter 32, contempt for those who do not think virtue is the sole good.
