Si todo el mundo piensa igual es que alguien no está pensando.

If everyone is thinking alike, then somebody isn’t thinking. George S. Patton

If we all think alike, no one is thinking.

Where all think alike, no one thinks very much. — WALTER LIPPMANN, The Stakes of Diplomacy

It would be a dull world if we all thought alike.

Nobody is thinking about you the way you are thinking about you. They’re all thinking about themselves.

A person who thinks all the time has nothing to think about except thoughts, so he loses touch with reality and lives in a world of illusions.

Não tenha medo de pensar diferente dos outros, tenha medo de pensar igual e descobrir que todos estão errados.

Everybody's the same. People are all the same. But it’s the prerogative of youth to think it’s not so.

Indeed it may be said with some confidence that the average man never really thinks from end to end of his life. There are moments when his cogitations are relatively more respectable than usual, but even at their climaxes they never reach anything properly describable as the level of serious thought. The mental activity of such people is only a mouthing of clichés. What they mistake for thought is simply a repetition of what they have heard. My guess is that well over eighty per cent. of the human race goes through life without having a single original thought. That is to say, they never think anything that has not been thought before and by thousands.

More often than not, it seems that people are having thoughts, though not really thinking about what they’re thinking about — at least not in an effective way that resolves, advances, or manages the content.

Young people get the foolish idea that what is new for them must be new for everybody else too. No matter how unconventional they get, they're just repeating what others before them have done.

Everybody is very much alike, really. But fortunately, perhaps, they don't realise it. - Miss Marple
