Quantity in diet is more to be regarded than quality. A full meal is a great enemy both to study and industry.

In this quote, Samuel Richardson argues that quantity in diet should be prioritized over quality, suggesting that consuming a larger amount of food may be more important than eating the most nutritious or high-quality foods. He goes on to assert that a full meal is detrimental, particularly for activities like study and industry. Richardson implies that heavy meals can make people feel sluggish, impairing their ability to focus and work efficiently, thus negatively affecting intellectual and professional pursuits.

Richardson’s viewpoint reflects an emphasis on moderation in eating. By describing a full meal as an "enemy" to productivity, he suggests that consuming large amounts of food can lead to lethargy, making it harder for individuals to engage in mentally demanding tasks or maintain high levels of efficiency in their work. His quote implies that light meals might be more conducive to sustained mental and physical performance.

The origin of this quote comes from Richardson's work as a writer during the 18th century. As a novelist, particularly known for his books Pamela and Clarissa, Richardson was keenly interested in the relationships between behavior, morality, and personal habits. This quote reflects the prevailing ideas of the time regarding the balance between indulgence and discipline, with an emphasis on maintaining mental clarity for tasks requiring focus and effort.

Ultimately, Richardson’s words suggest that eating habits have a significant impact on one’s ability to work and concentrate. His advice to avoid overindulgence and focus on smaller, more manageable meals aligns with the belief that moderation is key to both physical and mental well-being, especially when it comes to maintaining productivity in demanding activities.
