أستغفرُ اللهَ إلّا من محبّتِكم
فإنّها حسناتي يومَ ألقاه

فإنْ زَعمتُم بأنّ الحبَّ معصيةٌ
فالحبُّ أجملُ ما يُعصى به الله

— العباس بن الأحنف

وَيا رُبَّ يَومٍ قَد لَهَوتُ وَلَيلَةٍ
بِآنِسَةٍ كَأَنَّها خَطُّ تِمثالِ

— إمرؤ القيس

Pleasure and pain
By Leonardo da Vinci

I have said little about pleasure. Pain and pleasure are not twins or mirror images of each other, at least not as far as their roles in leveraging survival. Somehow, more often than not, it is the pain-related signal that steers us away from impending trouble, both at the moment and in the anticipated future. It is difficult to imagine that individuals and societies governed by the seeking of pleasure, as much as or more than by the avoidance of pain, can survive at all. Some current social developments in increasingly hedonistic cultures offer support for this opinion.
