The ninth essay from Lucius Annaeus Seneca. The work opens with Serenus asking Seneca for counsel, and this request for help takes the form of a medical consultation. Serenus explains that he feels agitated, and in a state of unstable immobility, "as if I were on a boat that doesn't move forward and is tossed about." Seneca uses the dialogue to address an issue that cropped up many times in his life: the desire for a life of contemplation and the need for active political engagement. Seneca argues that the goal of a tranquil mind can be achieved by being flexible and seeking a middle way between the two extremes.
