Hypothetical Propsootion, Arguments, and Inference Flashcards
second mental operation
judgement
statement that contain truth values in them
propositions
a kind of proposition that is aligned towards the properties of being present within a statement, which can be divided whether it is quality or quantity
categorical proposition
these are propositions that are entirely different to categorical ones since instead of an explicit dis-/agreement over the subject and predicate terms, it provides a tentative idea
hypothetical propositions
it can be further divided into conditional, disjunctive, or conjunctive propositions
hypothetical propositions
a kind of hypothetical proposition that expresses a logical relationship between an antecedent and a consequent
conditional propositions
Antecedent (Conditions) = “If”
and other expressions like
“unless”, “which”, etc
conditional propositions
Consequent (Results) =
“Then”, “Therefore”
conditional propositions
truth value is reliant on the relationship of the antecedent and the consequent
conditional proposition
suppose the antecedent is true, then the consequent should also be true
conditional proposition
suppose the antecedent is a cause (an action), the consequent should be true since this is a natural result of the antecedent
conditional propositions
___ propositions are either true or false
conditional propositions
A kind of hypothetical proposition
that contains two or more
alternatives which are so related
that one of them is true.
disjunctive propositions
Markings:
⊳ Either-or
⊳ Whether-or
⊳ Neither-nor
⊳ Or
disjunctive propositions
A kind of hypothetical proposition
that contains alternatives of which
only one must be true.
conjunctive propositions
Markings:
⊳ “And”
⊳ “can not be… at the same
time” or “cannot be both”
(referring to the
subjects/predicates)
conjunctive propositions
means to change it into its other forms, whether the given is one of the three kinds of hypothetical proposition.
reduction
is only of form/structure, and not of the proposition’s validity
reduction
a group of propositions which one proposition is claimed to follow from the other propositions which are regarded as providing support or ground for its truth
