Salvation is in logical, natural, and divine wisdom

Author's name: Ibn Sina Publisher: Afaq for Publishing and Distribution Year of publication: 2020 Literary classification: History and Philosophy Brief about the book: The philosopher Ibn Sina divided his book Al-Najat into three sections: Logic: In this section, Ibn Sina discussed, in the style of Aristotle, the term and the compound, before addressing the five terms. From this, he discusses the three categories of speech, which are the noun, the word (or the verb), and the tool. After that, he covers the three types of reasoning: conjunctive, exceptional, and conditional. He then discusses the premises on which reasoning is built, with its nine forms. Natural sciences: In this section, he begins by defining this science as a theoretical discipline, its subject being existing bodies, as they are subject to change, and described by various movements and rest states. This classification differs significantly from Aristotle’s, who limited the principles of natural science to matter, form, and non-existence. Ibn Sina begins the third section of his book Al-Najat by stating that the divine world differs from natural science and mathematical science, which investigate the states of some particular existences, in terms of examining the states of the absolute existence and its accessories, which are unity, multiplicity, power, action, eternity, temporality, cause, and effect.
