Contradictions of life itself and misunderstood polar opposites

The grandfather of a good friend used to say that everything in life is moved by contrasts and petty interests, by apparent contradictions, by opposites, and of course today I understand what he was referring to because there are always two poles, for example south and north, black and white, positive and negative, likes and dislikes, phobias and philias, in short, we place everything in categories of opposites because we consider that this way things can be better understood, this makes us enter into constant contradictions and we do not understand many things in life itself.

If we do not want to enter into contradictions with life itself, we must understand that we do not all think in the same way, that each one has his own way of acting, according to his convictions, and that none of this can lead to attacking the other, to pretending that he should disappear.
