This quote is a reflection on the impact of physical states on mental capacity and decision-making. It suggests that a person’s ability to think critically and act decisively is diminished after a full meal. This is because the body, post-meal, is focused on digestion, which can lead to feelings of lethargy and decreased mental acuity.

Franklin’s advice is to hold council, or make important decisions, before dinner when the mind is alert and not occupied with the process of digestion. It’s a reminder of the intimate connection between our physical and mental states, and how one can influence the other.

In today’s world, this idea could be applied in various ways. For example, in the business world, it might be more productive to schedule important meetings and decision-making sessions in the morning or before meals when participants are likely to be more alert and engaged.

In terms of personal development, it encourages us to be mindful of our physical state when engaging in tasks that require significant mental effort. It suggests that we should take care of our physical health in order to optimize our mental performance.

Moreover, it also hints at the concept of ‘decision fatigue’, a state of reduced efficacy in making decisions after a long session of decision making. Hence, it might be interpreted that it’s better to make important decisions when one is fresh and not under the influence of ‘decision fatigue’ or a full belly.

So, whether it’s a student deciding on their course of study, an employee planning their workday, or a CEO making strategic decisions, Benjamin Franklin’s wisdom still holds relevance. It’s about optimizing our physical and mental states to make the best decisions possible.
