Meditation 4.3
3. Men look for retreats for themselves, the country, the sea-shore, the hills; and you yourself, too, are peculiarly accustomed to feel the same want. Yet all this is very unlike a philosopher, when you may at any hour you please retreat into yourself. For nowhere does a man retreat into more quiet or more privacy than into his own mind, especially one who has within such things that he has only to look into, and become at once in perfect ease; and by ease I mean nothing else but good behaviour. Continually, therefore, grant yourself this retreat and repair yourself. But let them be brief and fundamental truths, which will suffice at once by their presence to wash away all sorrow, and to send you back without repugnance to the life to which you return.
For what is it that shall move your repugnance? The wickedness of men? Recall the judgement that reasonable creatures have come into the world for the sake of one another; that patience is a part of justice; that men do wrong involuntarily; and how many at last, after enmity, suspicion, hatred, warfare, have been laid out on their death-beds and come to dust. This should make you pause. But shall what is assigned from Universal Nature be repugnant to you? Revive the alternative: 'either Providence or blind atoms', and the many proofs that the Universe is a kind of Commonwealth. Shall then the things of the flesh still have hold upon you? Reflect that the understanding, when once it takes control of itself and recognizes its own power, does not mingle with the vital spirit, be its current smooth or broken, and finally reflect upon all that you have heard and consented to about pain and pleasure.
Well, then, shall mere glory distract you? Look at the swiftness of the oblivion of all men; the gulf of endless time, behind and before; the hollowness of applause, the fickleness and folly of those who seem to speak well of you, and the narrow room in which it is confined. This should make you pause. For the entire earth is a point in space, and how small a corner thereof is this your dwelling place, and how few and how paltry those who will sing your praises here!
Finally, therefore, remember your retreat into this little domain which is yourself, and above all be not disturbed nor on the rack, but be free and look at things as a man, a human being, a citizen, a creature that must die. And among what is most ready to hand into which you will look have these two: the one, that things do not take hold upon the mind, but stand without unmoved, and that disturbances come only from the judgement within; the second, that all that your eyes behold will change in a moment and be no more; and of how many things you have already witnessed the changes, think continually of that.
The Universe is change, life is opinion.
