Marcus Cato (Cato the Elder)

Plutarch's Lives of the Noble Romans

Cato the Elder (234 BCE – 149 BCE) was raised on a modest, rustic estate in the Sabine territory, deeply influenced by the memory of his neighbor, the legendary, simple-living commander Manius Curius Dentatus. Rejecting the growing luxury of Rome, the young man spent his days working his fields alongside his own slaves, eating the same coarse rations, and developing an iron-clad physical resilience. Cato thrust himself into public life as a relentless, aggressive prosecutor, launching over fifty legal indictments against elite aristocrats like Scipio Africanus to combat what he viewed as corrupting Greek influences. As Censor, he ran his household and the state like a strict military camp, investigating the private bedrooms of citizens and passing severe sumptuary laws to regulate dress and dining habits. He operated with a cold, utilitarian severity, notoriously advocating for the sale of old or sick slaves to save money on rations. A prolific orator who mastered the Greek language in his old age purely to combat its philosophy, he concluded every late-career speech with the unyielding declaration that Carthage must be destroyed, epitomizing the ultimate, unbending baseline of ancient Roman austerity.

Am relaxed most of the time.

Response:

Very inaccurate

5

AI-Generated Research:

Neuroticism - Item 7
Item:

Get upset easily.

Response:

Moderately inaccurate

Score:

2

AI-Generated Research:

Cato had a fierce, highly combative temper when confronting political corruption or moral decay, but he possessed an extraordinary threshold for personal insults and frustration, rarely letting his emotions compromise his focus. Plutarch relates an incident where a man struck Cato in the public bath; when the assailant later apologized, Cato calmly replied that he did not even remember being struck. He channeled his anger into structured, calculated legal prosecutions rather than allowing himself to be easily upset or provoked into petty, impulsive outbursts.

Neuroticism - Item 8
Item:

Have frequent mood swings.

Item:

Make a mess of things.

Response:

He executed his duties with surgical, unyielding accuracy, loathing any form of administrative messiness.

Conscientiousness - Item 10
Item:

Often forget to put things back in their proper place.

Response:

Very inaccurate

Score:

5

AI-Generated Research:

Given his obsessive perfectionism and rigorous accounting methods, personal carelessness or physical disorganization is entirely incompatible with Cato's profile. Plutarch notes that Cato personally inspected his estate’s accounts down to the penny, maintained a flawless inventory of his property, and wrote a comprehensive, highly organized manual on farming (De Agri Cultura). A mind that mathematically managed every grain of wheat and piece of farm equipment would naturally maintain absolute physical order.

Conscientiousness - Item 11
Item:

Like order.

Response:

Very accurate

Score:

5

AI-Generated Research:

Cato was a fanatical champion of absolute, unyielding order and structural discipline. Plutarch documents that his entire household was run like a strict military camp, with slaves assigned precise duties and forbidden from leaving the house without permission. He applied this extreme passion for order to the Roman state by passing severe sumptuary laws that strictly regulated what citizens could wear, how much they could spend on feasts, and how they maintained public infrastructure, seeking to lock Roman society into a permanent, highly ordered moral mold.

Get chores done right away.

Response:

Very accurate

Score:

5

Item:

Am not interested in other people's problems.

Response:

Moderately accurate

Score:

2

AI-Generated Research:

Cato was deeply invested in resolving the macro-level structural and moral problems of the Roman state, but he was profoundly indifferent—and often hostile—to the individual, emotional, or financial misfortunes of ordinary people. If a citizen fell into debt or poverty due to luxury or a lack of hard labor, Cato viewed their problem as a moral failing deserving of public shame rather than assistance. He believed individuals should stoically endure their hardships without expecting communal sympathy or relief.

Agreeableness - Item 14
Item:

Am not really interested in others.

Response:

Very inaccurate

Score:

5

AI-Generated Research:

Cato maintained an intense, highly intrusive preoccupation with the behavior, morals, and private lives of everyone around him. Rather than ignoring others, he observed them with pathological scrutiny. Plutarch notes that during his censorship, Cato took it upon himself to investigate what citizens did in the privacy of their own bedrooms, famously expelling a senator from the curia merely for kissing his own wife in public during the daytime, proving an obsessive interest in controlling human behavior.

Item:

Feel others' emotions.

Response:

Very inaccurate

Score:

1

AI-Generated Research:

Cato possessed an incredibly rigid, emotionally impermeable psychological structure that was completely immune to absorbing or mirroring the passions, griefs, or fears of those around him.

Sympathize with others' feelings.

Response:

Very inaccurate

Cato explicitly advocated for selling off old, sick, or worn-out slaves to save money on their rations, proving he viewed human suffering through a lens of absolute financial calculation rather than emotional sympathy.

Extraversion - Item 17
Item:

Keep in the background.

Response:

Very inaccurate

Score:

5

AI-Generated Research:

Cato possessed a fierce, aggressive drive to occupy the absolute forefront of Rome's political and moral landscape. Plutarch details his career as a relentless prosecutor who launched over fifty legal indictments against high-profile figures, including the legendary Scipio Africanus.

Extraversion - Item 18
Item:

Don't talk a lot.

Response:

Moderately inaccurate

Item:

Talk to a lot of different people at parties.

Response:

Very inaccurate

Score:

1

AI-Generated Research:

Cato systematically avoided casual parties and broad social mingling, preferring a lifestyle of rigid isolation from Rome's evolving elite social circles. Plutarch notes that he spent his evenings working his fields alongside his slaves or practicing law and statecraft. When he did attend mandatory civic dinners or host small gatherings at his country estate, his conversation was heavily restricted to praising the virtues of ancient Roman heroes and lecturing his guests on agricultural economy and moral discipline, entirely avoiding casual, inclusive socializing.

Extraversion - Item 20
Item:

Am the life of the party.

Response:

Very inaccurate

Score:

1

AI-Generated Research:

Cato the Elder was the ultimate antithesis of a party-goer, actively despising luxury, revelry, and social extravagance. Plutarch notes that he chose to live in a simple cottage, drank the same cheap wine as his laborers, and famously proclaimed that he would rather go unrewarded for a good deed than unpunished for a bad one. He viewed lighthearted banquets and social merriment as dangerous sources of Greek effeminacy that eroded traditional Roman virtue, consistently positioning himself as a stern, judgmental critic of leisure rather than its life.
