How we cite our quotes: (Book.Chapter)
Quote #1
Similarly the ears of corn nodding down to the ground, the lion's puckered brow, the foam gushing from the boar's mouth, and much else besides—looked at in isolation these things are far from lovely, but their consequence on the processes of Nature enhances them and gives them attraction. So any man with a feeling and deeper insight for the workings of the whole will find some pleasure in almost every aspect of their disposition, including the incidental consequences. (3.2.2-3)
Marcus uses his philosophy as a platform to define himself and to learn what type of person he is. In this passage, he also shows the value of being able to really look at the things and people around us—and to find the value in each thing. His choice to focus on "unlovely" things illustrates Marcus's desire to get down to the substance of the things around him, without making value judgments on what he sees. To be able to do this with other people allows him more readily to do this in an assessment of himself.
Quote #2
Further, let the god that is within you be the champion of the being you are—a male, mature in years, a statesman, a Roman, a ruler: one who has taken his post like a soldier waiting for the Retreat from life to sound, and ready to depart, past the need for any loyal oath or human witness. (3.5)
Marcus makes a philosophical exercise of defining who he is. Note that he doesn't put particular emphasis on his state position; he gives equal billing to his citizenship and to his profession. He's just a regular guy, really, trying to do the right thing in his life until it is time to die. Which, by the way, he will do without ceremony. In this way, the Meditations is a remarkable piece of work. We have the leader of one of the mightiest empires on earth insisting on a generic human identity so that he can stay in harmony with his role as a citizen of the global city.
Quote #3
He is a fugitive if he runs away from social principle; blind, if he shuts the eye of the mind; a beggar, if he needs for life; a tumour on the universe, if he stands aside and separates himself from the principle of our common nature in disaffection with his lot...a social splinter, if he splits his own soul away from the soul of all rational beings, which is a unity. (4.29)
Marcus sees humans as essentially social creatures who must participate in the life of their communities and of the universe if they is to fulfill their designated roles. To kick against fate, to blame the gods or to separate yourself from other people is to deny your humanity and to turn yourself into something monstrous (like a tumor). It's a denial of rational nature, and it's something that Marcus will later speak of as a sin against both the self and the gods.
Quote #4
I am made up of the causal and the material. Neither of these will disappear into nothing. So every part of me will be assigned its changed place in some part of the universe, and that will change again into another part of the universe, and so on to infinity. (5.13)
Marcus speaks rather coldly of his future dissolution into his component parts. This is the thing that keeps him steady in the contemplation of his mortality and helps him to accept his role in the grand scheme of the universe. While there's no mention of a preservation of self in this scheme, Marcus does not seem too disturbed. There's still a chance that consciousness will be preserved, so to play a role in the renewal of the universe is part of human nature that we shouldn't fear.
Quote #5
Things of themselves cannot touch the soul at all. They have no entry to the soul, and cannot turn or move it. The soul alone turns and moves itself, making all externals presented to it cohere with the judgements it thinks worthy of itself. (5.19)
Marcus speaks of the mind and soul as closed systems, things that are not necessarily responsive to external concerns. This may sound antisocial, but Marcus points out the necessity of this isolation to the preservation of personal freedom. If you can keep your mind and soul walled off from the hubbub of the outside world, you'll never become dependent on the things of this world (wealth, fame, emotional drama). This will allow you to be more authentically yourself, the being created by the Whole for a specific purpose in the universe.
Quote #6
And do not think, just because you have given up hope of becoming a philosopher or a scientist, you should therefore despair of a free spirit, integrity, social conscience, obedience to god. It is wholly possible to become a 'divine man' without anybody's recognition. (7.67)
Marcus is clearly having a struggle with his identity and role in life. He's born to be a leader and live an active life, but he's drawn to a contemplative life of study. This, unfortunately, cannot be. Marcus finds himself in the position that many of us in the modern world understand: how can he balance all the parts of his life and personality? How can he run the Roman Empire and plumb the depths of philosophical truths? Marcus decides that on the most basic level, philosophy is about a life well lived, according to one's principles. He's pretty sure he can swing that, even while fighting off hostile tribes on the frontier.
Quote #7
Every living organism is fulfilled when it follows the right path for its own nature. For a rational nature the right path is to withhold assent to anything false or obscure in the impressions made on the mind, to direct its impulses solely to social action, to reserve its desires and aversions to what lies in our power, and to welcome all that is assigned to it by universal nature. (8.7)
Marcus is big on following nature, since nature is the thing that defines your mind and your purpose in life. Because we're all given a rational mind, the goal is to live according to the precepts of reason. And the first rule of reason is to live life as a social being, working always for the common good. It's just an inescapable part of human identity, and one that must be accepted if we're is to live life in accordance with the plans of the universe.
Quote #8
But as things are you see how wearisome it is to live out of tune with your fellows, so that you say: 'Come quickly, death, or I too may forget myself.' (9.3.2)
Although everyone is given the same spark of divinity (reason), Marcus can't help feeling like the odd man out in his society. Perhaps it's because he's the emperor—that would certainly set him apart. It could also be because he's working hard to live a life according to principles that others don't value, or it could be because others have chosen to ignore their duty to live life in a rational manner. Either way, Marcus is having a hard time sticking to his philosophical regime in a world full of yahoos. He also fears that these fools may begin to change him (not for the better) before he can make it to the end of his life.
Quote #9
Remember that what pulls the strings is that part of us hidden inside: that is the power to act, that is the principle of life, that, one could say, is the man himself. (10.38)
Marcus talks about the rational soul here (which overlaps in many ways with the "directing mind") as the thing that gives life and purpose to our motion in the world. It's what we might simply call the soul these days—the vital power in us that we can't see or touch but that may endure separately from the body. It's also the thing that houses our personality—"the man himself"—the part that defines us as individuals. For all his talk about the commonality of human purpose and experience, Marcus is a strong believer in self-definition, without reference to the outside world.
Quote #10
If, then, when you finally come close to your exit, you have left all else behind and value only your directing mind and the divinity within you, if your fear is not that you will cease to live, but that you never started a life in accordance with nature, then you will be a man worthy of the universe that gave you birth. You will no longer be a stranger in your own country... (12.2)
Marcus has spoken before about being a "stranger in a strange land." He especially feels this when he's confronted with things like the transience of human existence. At the very end of this work, he's found the antidote for this feeling of alienation: becoming what the gods intend, by acknowledging what we have in common with them. In this case, it's reason. If Marcus can live his life in accordance with his principles, he will become more himself—more in tune with the true nature of a man.
