The Essays is a collection of short prose pieces, each headed Of followed by a single subject, such as truth, death, revenge, adversity, great place, friendship, and studies. Bacon offers them as counsels rather than systematic philosophy, dedicating them with the claim that they come home to men's business and bosoms.
The method is compact and aphoristic. Each essay states a thesis, presses it with classical and biblical examples, and turns it over from several angles. Bacon rarely tells a story; he assembles maxims, distinctions, and observations, often in Latin tags, into a dense argument that rewards slow reading more than a continuous narrative would.
A persistent theme is the gap between appearance and reality, and the prudence needed to navigate it. Truth is a naked daylight that men avoid because a mixture of lie adds pleasure; dissimulation is the weaker sort of policy; in great place a person is watched, envied, and a stranger to himself. Bacon repeatedly weighs the practical cost of each course.
Several essays examine conduct in society and power. Of Revenge counsels passing over wrongs as the prince's part; Of Great Place warns that authority is servitude whose only good end is doing good, and lists the vices of authority as delays, corruption, roughness, and facility. Of Friendship treats a true friend as the one receipt that opens a burdened heart.
The most famous essay, Of Studies, sets out how learning should be used: studies serve for delight, ornament, and ability, and are perfected by experience. Reading makes a full man, conference a ready man, writing an exact man. Taken together the essays form a worldly, often skeptical handbook of judgment for a person who must live and act among others.
