Pleasure is a feeling of contentment that one achieves whenever information in consciousness says that expectations set by biological programs or by social conditioning have been met. The taste of food when we are hungry is pleasant because it reduces a physiological imbalance. Resting in the evening while passively absorbing information from the media, with alcohol or drugs to dull the mind overexcited by the demands of work, is pleasantly relaxing.
