| The name "Fesapo" is a [[wp>Mnemonic|mnemonic]] term that helps to remember the most important characteristics of this mode: The "F" at the beginning indicates that it is related to the [[logic:inferences:modus_ferio:index|Modus Ferio]], while the vowels indicate the types of statements used in the form: "e" and "a" stand for a //negative// and //affirmative// [[glossary:universal_quantification|universal]] premisses and the "o" for a negative [[logic:glossary:existential_quantification|existential]] conclusion. | The name "Fesapo" is a [[wp>Mnemonic|mnemonic]] term that helps to remember the most important characteristics of this mode: The "F" at the beginning indicates that it is related to the [[logic:inferences:modus_ferio:index|Modus Ferio]], while the vowels indicate the types of statements used in the form: "e" and "a" stand for a //negative// and //affirmative// [[glossary:universal_quantification|universal]] premisses and the "o" for a negative [[glossary:existential_quantification|existential]] conclusion. |
