Seneca

His own words, in a letter to Lucilius

In plain words, ours

Crowds are bad for you: someone always makes a bad habit look good or rubs it off on you without you noticing. The bigger the crowd, the bigger the risk.

To consort with the crowd is harmful; there is no person who does not make some vice attractive to us, or stamp it upon us, or taint us unconsciously therewith. Certainly, the greater the mob with which we mingle, the greater the danger.

“What progress, you ask, have I made? I have begun to be a friend to myself.” That was indeed a great benefit; such a person can never be alone. You may be sure that such a man is a friend to all mankind. Farewell. Do you ask me what you should regard as especially to be avoided? I say, crowds; for as yet you cannot trust yourself to them with safety. I shall admit my own weakness, at any rate; for I never bring back home the same character that I took abroad with me. Something of that which I have forced to be calm within me is disturbed; some of the foes that I have routed return again. Just as the sick man, who has been weak for a long time, is in such a condition that he cannot be taken out of the house without suffering a relapse, so we ourselves are affected when our souls are recovering from a lingering disease.

The quote: To consort with the crowd is harmful; there is no person who does not make some vice attractive to us, or stamp it upon us, or taint us unconsciously therewith. Certainly, the greater the mob with which we mingle, the greater the danger.

But nothing is so damaging to good character as the habit of lounging at the games; for then it is that vice steals subtly upon one through the avenue of pleasure. What do you think I mean? I mean that I come home more greedy, more ambitious, more voluptuous, and even more cruel and inhuman,—because I have been among human beings. By chance I attended a mid-day exhibition, expecting some fun, wit, and relaxation,—an exhibition at which men’s eyes have respite from the slaughter of their fellow-men. But it was quite the reverse.
