Salvēte, discipulī cārissimī.
Ā quālitātibus physicīs nunc ad quālitātēs sermōnis et vēritātis prōgredimur. Hominēs nōn sōlum in mundō physicō vīvunt—etiam in mundō verbōrum et idēārum vīvunt. Sermō potest esse iocōsus vel sērius. Historia potest esse certa aut dubia. Testimōnium potest esse vērum vel falsum.
From physical qualities we now proceed to the qualities of speech and truth. Humans do not live only in the physical world—they also live in the world of words and ideas. A speech can be merry or serious. A history can be certain or doubtful. A testimony can be true or false.
Haec verba sunt fundamenta sapientiae—nam quī vērum ā falsō discernere nōn potest, sapiēns nōn est.
These words are the foundations of wisdom—for he who cannot distinguish the true from the false is not wise.

This lesson presents three important antonym pairs relating to communication and truth:
Positive Meaning Negative Meaning iocōsus, -a, -um merry, jesting sērius, -a, -um serious certus, -a, -um certain, sure dubius, -a, -um doubtful vērus, -a, -um true falsus, -a, -um false
Sermō is a third declension masculine noun meaning “speech, conversation, discourse”:
Case Singular Plural Nominative sermō sermōnēs Genitive sermōnis sermōnum Dative sermōnī sermōnibus Accusative sermōnem sermōnēs Ablative sermōne sermōnibus
Note: Sermō emphasizes conversational speech, while ōrātiō refers to formal oratory.
Historia, -ae (f.) — originally “inquiry” (from Greek ἱστορία), came to mean “history, narrative of past events.”
Testimōnium, -iī (n.) — “testimony, evidence, witness” (from testis, “witness”).
The pair vērus/falsus is one of the most important in Latin: -
vērus = true, real, genuine -
falsus = false, deceptive, counterfeit
Related forms: -
vēritās, vēritātis (f.) = truth -
falsitās, falsitātis (f.) = falsehood -
vērē (adv.) = truly -
falsō (adv.) = falsely

Morāle: The moral: “Sermō “A speech sērius serious nōn not semper always vērus true est. is. Sermō A speech iocōsus merry nōn not semper always falsus false est. is. Sapiēns The wise man omnia all things exāminat.” examines.”
Ōlim iūdex quīdam trēs testēs audīvit. Once upon a time a certain judge heard three witnesses.
Causa erat gravis: homō accūsātus erat fūrtī. The case was serious: a man had been accused of theft.
Prīmus testis accessit. Sermō eius erat sērius et gravis. The first witness approached. His speech was serious and weighty.
“Vīdī,” inquit, “accūsātum aurum rapientem. Testimōnium meum est vērum. Historia est certa.” “I saw,” he said, “the accused seizing gold. My testimony is true. The story is certain.”
Secundus testis accessit. Sermō eius erat iocōsus et levis. The second witness approached. His speech was merry and light.
“Fortasse,” inquit rīdēns, “vīdī aliquid. Fortasse nōn. Quis scit? Historia est dubia.” “Perhaps,” he said laughing, “I saw something. Perhaps not. Who knows? The story is doubtful.”
Tertius testis accessit. Sermō eius erat et sērius et iocōsus. The third witness approached. His speech was both serious and merry.
“Iūdex,” inquit, “prīmus testis dīcit sē vīdisse.” “Judge,” he said, “the first witness says that he saw.”
“Sed ego eōdem tempore in eōdem locō eram. Nihil vīdī.” “But I was in the same place at the same time. I saw nothing.”
“Quōmodo ille vidēre potuit quod ego vidēre nōn potuī?” “How could that man see what I could not see?”
Iūdex cōgitāvit. The judge thought.
“Prīmum testimōnium,” inquit, “vidētur vērum sed est dubium.” “The first testimony,” he said, “seems true but is doubtful.”
“Secundum testimōnium est apertē dubium.” “The second testimony is openly doubtful.”
“Tertium testimōnium ostendit prīmum fortasse falsum esse.” “The third testimony shows that the first is perhaps false.”
“Historia certa ex testimōniīs dubiīs nōn fit.” “A certain story is not made from doubtful testimonies.”
Accūsātus līberātus est. The accused was freed.
Morāle: “Sermō sērius nōn semper vērus est. Sermō iocōsus nōn semper falsus est. Sapiēns omnia exāminat.” Moral: “A serious speech is not always true. A merry speech is not always false. The wise man examines all things.”
Ōlim iūdex quīdam trēs testēs audīvit. Causa erat gravis: homō accūsātus erat fūrtī.
Prīmus testis accessit. Sermō eius erat sērius et gravis. “Vīdī,” inquit, “accūsātum aurum rapientem. Testimōnium meum est vērum. Historia est certa.”
Secundus testis accessit. Sermō eius erat iocōsus et levis. “Fortasse,” inquit rīdēns, “vīdī aliquid. Fortasse nōn. Quis scit? Historia est dubia.”
Tertius testis accessit. Sermō eius erat et sērius et iocōsus. “Iūdex,” inquit, “prīmus testis dīcit sē vīdisse. Sed ego eōdem tempore in eōdem locō eram. Nihil vīdī. Quōmodo ille vidēre potuit quod ego vidēre nōn potuī?”
Iūdex cōgitāvit.
“Prīmum testimōnium,” inquit, “vidētur vērum sed est dubium. Secundum testimōnium est apertē dubium. Tertium testimōnium ostendit prīmum fortasse falsum esse.”
“Historia certa ex testimōniīs dubiīs nōn fit.”
Accūsātus līberātus est.
Morāle: “Sermō sērius nōn semper vērus est. Sermō iocōsus nōn semper falsus est. Sapiēns omnia exāminat.”
The fable teaches epistemic humility: the tone of speech (sērius/iocōsus) does not determine its truth value (vērus/falsus). A serious speaker may lie; a jesting speaker may tell truth. The wise judge evaluates content, not manner.
This reflects Comenius’s emphasis on critical thinking—students should learn to evaluate claims on their merits, not on how confidently they are delivered.

DISCIPULUS: Magister, Master, quid what est is differentia the difference inter between “iocōsum” “merry” et and “sērium”? “serious”?
COMĒNIUS: “Iocōsus” “Merry” ē from “iocus” “jest” venit. comes. Sermō A speech iocōsus merry rīsum laughter movet. moves. “Sērius” “Serious” contrārium the contrary est. is. Sermō A speech sērius serious dē about rēbus things gravibus weighty agit. deals.
DISCIPULUS: Et And “certus” “certain” et and “dubius”? “doubtful”?
COMĒNIUS: “Certus” “Certain” significat means “sine “without dubiō.” doubt.” Rēs A thing certa certain est is rēs a thing quam which scīmus we know vēram true esse. to be. “Dubius” “Doubtful” significat means “cum “with dubiō.” doubt.” Rēs A thing dubia doubtful est is rēs a thing dē about quā which nōn not certī certain sumus. we are.
DISCIPULUS: Ergō Therefore “dubius” “doubtful” nōn not est is idem the same ac as “falsus”? “false”?
COMĒNIUS: Minimē! Not at all! Rēs A thing dubia doubtful potest can esse be vēra. true. Rēs A thing dubia doubtful potest can esse be falsa. false. Nōndum Not yet scīmus. do we know. “Falsus” “False” autem however significat means “nōn “not vērus.” true.” Rēs A thing falsa false nōn not est is dubia doubtful —est —it is certē certainly nōn not vēra. true.
DISCIPULUS: Intellegō! I understand! “Dubius” “Doubtful” est is inter between “vērum” “true” et and “falsum.” “false.”
COMĒNIUS: Praecīsē! Precisely! Sapiēns The wise man trēs three habet has categoriās: categories: VĒRUM TRUE —quod —which certē certainly scit. he knows. FALSUM FALSE —quod —which certē certainly negat. he denies. DUBIUM DOUBTFUL —quod —which nōndum not yet scit. he knows.
DISCIPULUS: Et And historia? history? Quōmodo How scīmus do we know historiam a history vēram true esse? to be?
COMĒNIUS: Quaestiō A question difficilis! difficult! Historia A history certa certain fit becomes ex from testimōniīs testimonies multīs. many. Sī If ūnus one testis witness dīcit, speaks, historia the history est is dubia. doubtful. Sī If multī many testēs witnesses idem the same thing dīcunt, speak, historia the history fit becomes certior. more certain. Sed But etiam even multī many testēs witnesses errāre to err possunt. can.
DISCIPULUS: Ergō Therefore numquam never certī certain esse to be possumus? can we?
COMĒNIUS: Sapiēns The wise man est is semper always humilis. humble. Dīcit: He says: “Haec “This historia story vidētur seems vēra true —sed —but ego I errāre to err possum.” can.” Haec This est is vēra true sapientia. wisdom.
DISCIPULUS: Grātiās Thanks tibi to you agō, I give, magister! master!
COMĒNIUS: Sermō The speech noster our fuit has been sērius serious —sed —but spērō I hope etiam also ūtilis! useful!
DISCIPULUS: Magister, quid est differentia inter “iocōsum” et “sērium”? STUDENT: Master, what is the difference between “merry” and “serious”?
COMĒNIUS: “Iocōsus” ē “iocus” venit. Sermō iocōsus rīsum movet. “Sērius” contrārium est. Sermō sērius dē rēbus gravibus agit. COMENIUS: “Merry” comes from “jest.” A merry speech moves laughter. “Serious” is the contrary. A serious speech deals with weighty things.
DISCIPULUS: Et “certus” et “dubius”? STUDENT: And “certain” and “doubtful”?
COMĒNIUS: “Certus” significat “sine dubiō.” Rēs certa est rēs quam scīmus vēram esse. “Dubius” significat “cum dubiō.” Rēs dubia est rēs dē quā nōn certī sumus. COMENIUS: “Certain” means “without doubt.” A certain thing is a thing which we know to be true. “Doubtful” means “with doubt.” A doubtful thing is a thing about which we are not certain.
DISCIPULUS: Ergō “dubius” nōn est idem ac “falsus”? STUDENT: Therefore “doubtful” is not the same as “false”?
COMĒNIUS: Minimē! Rēs dubia potest esse vēra. Rēs dubia potest esse falsa. Nōndum scīmus. “Falsus” autem significat “nōn vērus.” Rēs falsa nōn est dubia—est certē nōn vēra. COMENIUS: Not at all! A doubtful thing can be true. A doubtful thing can be false. We do not yet know. “False,” however, means “not true.” A false thing is not doubtful—it is certainly not true.
DISCIPULUS: Intellegō! “Dubius” est inter “vērum” et “falsum.” STUDENT: I understand! “Doubtful” is between “true” and “false.”
COMĒNIUS: Praecīsē! Sapiēns trēs habet categoriās: VĒRUM—quod certē scit. FALSUM—quod certē negat. DUBIUM—quod nōndum scit. COMENIUS: Precisely! The wise man has three categories: TRUE—which he certainly knows. FALSE—which he certainly denies. DOUBTFUL—which he does not yet know.
DISCIPULUS: Et historia? Quōmodo scīmus historiam vēram esse? STUDENT: And history? How do we know a history to be true?
COMĒNIUS: Quaestiō difficilis! Historia certa fit ex testimōniīs multīs. Sī ūnus testis dīcit, historia est dubia. Sī multī testēs idem dīcunt, historia fit certior. Sed etiam multī testēs errāre possunt. COMENIUS: A difficult question! A certain history becomes from many testimonies. If one witness speaks, the history is doubtful. If many witnesses say the same thing, the history becomes more certain. But even many witnesses can err.
DISCIPULUS: Ergō numquam certī esse possumus? STUDENT: Therefore we can never be certain?
COMĒNIUS: Sapiēns est semper humilis. Dīcit: “Haec historia vidētur vēra—sed ego errāre possum.” Haec est vēra sapientia. COMENIUS: The wise man is always humble. He says: “This story seems true—but I can err.” This is true wisdom.
DISCIPULUS: Grātiās tibi agō, magister! STUDENT: I thank you, master!
COMĒNIUS: Sermō noster fuit sērius—sed spērō etiam ūtilis! COMENIUS: Our speech has been serious—but I hope also useful!
DISCIPULUS: Magister, quid est differentia inter “iocōsum” et “sērium”?
COMĒNIUS: “Iocōsus” ē “iocus” venit. Sermō iocōsus rīsum movet. “Sērius” contrārium est. Sermō sērius dē rēbus gravibus agit.
DISCIPULUS: Et “certus” et “dubius”?
COMĒNIUS: “Certus” significat “sine dubiō.” Rēs certa est rēs quam scīmus vēram esse. “Dubius” significat “cum dubiō.” Rēs dubia est rēs dē quā nōn certī sumus.
DISCIPULUS: Ergō “dubius” nōn est idem ac “falsus”?
COMĒNIUS: Minimē! Rēs dubia potest esse vēra. Rēs dubia potest esse falsa. Nōndum scīmus. “Falsus” autem significat “nōn vērus.” Rēs falsa nōn est dubia—est certē nōn vēra.
DISCIPULUS: Intellegō! “Dubius” est inter “vērum” et “falsum.”
COMĒNIUS: Praecīsē! Sapiēns trēs habet categoriās: VĒRUM—quod certē scit. FALSUM—quod certē negat. DUBIUM—quod nōndum scit.
DISCIPULUS: Et historia? Quōmodo scīmus historiam vēram esse?
COMĒNIUS: Quaestiō difficilis! Historia certa fit ex testimōniīs multīs. Sī ūnus testis dīcit, historia est dubia. Sī multī testēs idem dīcunt, historia fit certior. Sed etiam multī testēs errāre possunt.
DISCIPULUS: Ergō numquam certī esse possumus?
COMĒNIUS: Sapiēns est semper humilis. Dīcit: “Haec historia vidētur vēra—sed ego errāre possum.” Haec est vēra sapientia.
DISCIPULUS: Grātiās tibi agō, magister!
COMĒNIUS: Sermō noster fuit sērius—sed spērō etiam ūtilis!
The colloquium presents a three-part classification of knowledge: -
VĒRUM: what we know to be true -
FALSUM: what we know to be false -
DUBIUM: what we do not yet know
This tripartite division is foundational to critical thinking.
The dialogue concludes with the principle of epistemic humility: even when we believe something to be true, we should acknowledge the possibility of error. This is not skepticism but wisdom—the recognition that human knowledge is always provisional.
-
The speech is serious. -
The history is doubtful. -
The testimony is true. -
Is this story certain or doubtful? -
The witness says that the accused is guilty.
