THE PROPOSITIONAL LOGIC OF AVICENNA – Book Sample

## Explaining the Meaning of the Universal, the Particular, the Indefinite and the Singular [Connective-]

Conditional Proposition

A certain view on how to determine the quantity of a connective proposition. His view on this issue – When is a conditional considered universal or indefinite?

– When is the conditional regarded as singular? – A criticism of the view that a universal connective is equal to a universal predicative – The universal affirmative connective proposition –

Can a connective expressing chance connection be universally affirmed? – Is ‘Always: when every donkey talks, then every man brays’ true in either one of the senses of following? – An objection and an answer related to the above issue – A proposition expressing chance connection is true when the consequent is true –

The antecedent of a connective proposition is not a statement-making sentence – A return to the discussion of universal affirmative connective propositions – Would they be affected if impossible conditions are added to their antecedents?

Particular Connective Propositions: The first kind of particular connective propositions –

The second kind of particular connective propositions – Is it

possible for the particular connective to have universal parts?

## On the Syllogisms Compounded of Connective and Separative Propositions *– THE PROPOSITIONAL LOGIC OF AVICENNA*

When the minor is connective and the major a real separative; and the middle part is the consequent of the minor and the antecedent of the major – **IA/I **– Al/- – It is productive when either one of the premises is particular – No production when the separative is negative –

No production from two negative or two particular premises – When the minor is connective and the major is unreal separative; and the middle part is the consequent of the first and the antecedent of the second – Sterile moods – The connective is particular – The separative is particular – No production when the separative is negative –

No production when the premises are particular – The same figure but the middle is negative – When the premises are affirmative and one of them is universal it will be sterile – and when one of them is particular it will be sterile – When the separative is negative it is sterile – When the parts of the separative are negative

– When the separative is real and the middle part is the antecedent of both premises – When either one of the premises is particular – When the separative is particular – When the separative is unreal and the middle part in the same position and it is affirmative – The separative is particular – The connective is particular –

No production when the separative is negative – Now the middle part is negative – One of the premises is particular – When the connective is negative and one of the premises is particular – No production when the sepa- rative is negative – The separative with both parts negative – When the connec- tive is the major premiss and the middle part is the antecedent of both – The separative is particular – The connective is particular – The connective is par ticular negative – When the separative is unreal and the middle is in the same position – The separative is particular – No production when the connective is particular – No production when the separative is negative – The separative is particular – No production when the connective is particular – When the middle is negative and it is the consequent of the first and the antecedent of the second – The separative is particular –

No production when the connective is particular – No production when the separative is negative – The separative is particular negative – No production when the connective is particular negative – When the separative is real and the middle is the consequent of both premises – The separative is particular -The connective is particular – No production when the separative is negative – The separative is particular negative – The connective is particular negative – When the separative is unreal and the middle is the con sequent of both premises and it is affirmative –

The separative is particular –

The connective is particular.
