Men are disturbed, not by things, but by the principles and notions

Men are disturbed, not by things, but by the principles and notions which they form concerning things. (5). (Enchiridion 5)

Men are disturbed not by the things which happen, but by the opinion about the things.

Men are disturbed not by the things that happen, but by their opinion of the things that happen.

Men are disturbed not by things, but by the view which they take of them.

What disturbs men's minds is not events but their judgements on events:

Men are disturbed not by things, but by the views which they take of things. Thus death is nothing terrible, else it would have appeared so to Socrates. But the terror consists in our notion of death, that it is terrible. When, therefore, we are hindered, or disturbed, or grieved let us never impute it to others, but to ourselves; that is, to our own views. It is the action of an uninstructed person to reproach others for his own misfortunes; of one entering upon instruction, to reproach himself; and of one perfectly instructed, to reproach neither others or himself.

People feel disturbed not by things, but by the views they take of them.

What disturbs men's minds is not events but their judgements on events: For instance, death is nothing dreadful, or else Socrates would have thought it so. No, the only dreadful thing about it is men's judgement that it is dreadful. And so when we are hindered, or disturbed, or distressed, let us never lay the blame on others, but on ourselves, that is, on our own judgements. To accuse others for one's own misfortunes is a sign of want of education; to accuse oneself shows that one's education has begun; to accuse neither oneself nor others shows that one's education is complete.

We are disturbed not by what happens to us, but by our thoughts about what happens.

Man is troubled not by events, but by the meaning he gives to them.

It is not activity that makes men restless, but false conceptions of things render them mad.

People are not disturbed by things themselves, but by the views they take of those things.

Men's views of things are the result of their understanding alone. Their conduct is regulated by their understanding, their temper, and their passions.
