Avicenna's legacy in classical psychology is primarily embodied in the Kitab al-nafs parts of his Kitab al-shifa (The Book of Healing) and Kitab al-najat (The Book of Deliverance). These were known in Latin under the title De Anima (treatises "on the soul").[dubious – discuss] Notably, Avicenna develops what is called the "flying man" argument in the Psychology of The Cure I.1.7 as defense of the argument that the soul is without quantitative extension, which has an affinity with Descartes's cogito argument (or what phenomenology designates as a form of an "epoche").
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What subject is never seen throughout Avicenna's Book of Healing?
Ah, so.. unanswerable

The Arsacid Kingdom of Armenia, itself a branch of the Arsacid dynasty of Parthia, was the first state to adopt Christianity as its religion (it had formerly been adherent to Armenian paganism, which was influenced by Zoroastrianism, while later on adopting a few elements regarding identification of its pantheon with Greco-Roman deities). in the early years of the 4th century, likely AD 301, partly in defiance of the Sassanids it seems. In the late Parthian period, Armenia was a predominantly Zoroastrian-adhering land, but by the Christianisation, previously predominant Zoroastrianism and paganism in Armenia gradually declined. Later on, in order to further strengthen Armenian national identity, Mesrop Mashtots invented the Armenian alphabet, in 405 AD. This event ushered the Golden Age of Armenia, during which many foreign books and manuscripts were translated to Armenian by Mesrop's pupils. Armenia lost its sovereignty again in 428 AD to the rivalling Byzantine and Sassanid Persian empires, until the Muslim conquest of Persia overran also the regions in which Armenians lived.

Ah, so.. Zoroastrianism

Russian (ру́сский язы́к, russkiy yazyk, pronounced [ˈruskʲɪj jɪˈzɨk] ( listen)) is an East Slavic language and an official language in Russia, Belarus, Kazakhstan, Kyrgyzstan and many minor or unrecognised territories. It is an unofficial but widely-spoken language in Ukraine, Latvia, Estonia, and to a lesser extent, the other countries that were once constituent republics of the Soviet Union and former participants of the Eastern Bloc. Russian belongs to the family of Indo-European languages and is one of the three living members of the East Slavic languages. Written examples of Old East Slavonic are attested from the 10th century onwards.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many living East Slavic languages are there?
Ah, so..
three
