By idea, I mean the mental conception which is formed by the mind as a thinking thing
Humans experience pleasure from a variety of stimuli, including food, money, and psychoactive drugs. Such pleasures are largely made possible by a brain chemical called dopamine, which activates what is known as the mesolimbic system — a network of interconnected brain regions that mediate reward. Most often, rewarding stimuli are biologically necessary for survival (such as food), can directly stimulate activity of the mesolimbic system (such as some psychoactive drugs), or are tangible items (such as money).
However, humans can experience pleasure from more abstract stimuli, such as art or music, which do not fit into any of these categories. Such stimuli have persisted across countless generations and remain important in daily life today. Interestingly, the experience of pleasure from these abstract stimuli is highly specific to cultural and personal preferences.
