العالم كلّه مسرح، والرجال والنساء فيه مجرّد ممثلين؛ لكلٍّ منهم خروجه ودخوله، ويؤدّي الإنسان في عمره أدوارًا كثيرة، فتكون أفعاله سبعة أطوار.

“All the world's a stage, and all the men and women merely players: they have their exits and their entrances; and one man in his time plays many parts, his acts being seven ages.”William Shakespeare
