Although Aristotle born 322 BCE had suggested that all colors can be aligned with one line from black to white, Ibn-Sina d. 1037 explained that there were three lines from black to white, one way in gray, a. the second method in red and the third method in green.
Al-Tusi c. 1258 stated that there are no less than five such methods, lemon yellow, blood red, pistachio green, indigo blue, and gray.
This text, which was copied in the Middle East several times until at least the nineteenth century as part of Kamal al-Din al-Farisi's book Revan of the Optics Tanqih al-Manazi d. 1320, created a color space. three-dimensional.
Robert Grosseteste d. 1253 proposed a successful three-dimensional model of color space. In his book Akhlaq-i Nasiri, Tusi wrote about a number of biological topics.
He defended Aristotle's version of the scala naturae, which placed man above animals, plants, minerals, and objects. He described “grass that grows without sowing or planting, just by mixing nutrients,” as being too close to minerals.
Among the plants, he regarded the palm tree as a highly developed tree, for “it lacked only one thing to reach the stage of the animal: to pluck itself from the ground and from there to feed. "
The lowest animals "are near the vegetation area those that are grass-fed can mate, eg worms, and certain insects". Animals that “reach the stage of perfection are distinguished by fully developed weapons”, such as horns, horns, teeth, and claws.
Tusi described these organs as adapting to a different kind of lifestyle, in a way that was in line with naturalistic theology. He continued
"The best thing about this kind of thing is that the one whose mind and attitude is to accept discipline and instruction: thus there is a perfection that was not created in the first place. Such is the trained horse and trained cash.
To look at the action is sufficient as an order: therefore, when they see something, they do like it, without training This is the highest level of animals, and the first qualifications of the person in accordance with it. "
Therefore, in this section, Tusi described different types of learning, recognizing cognitive learning as the most advanced method, and appropriately referring to specific animals.
Tusi seems to see that man is an animal because he said that the "Soul of Animal which includes the power of perception and movement is limited to animal species", and that, by being "Man". The soul, humanity is distinct and unique among other animals. "
Some scholars have interpreted Tusi's biological texts as suggesting that he adhered to a certain form of evolutionary theory.
However, Tusi did not explicitly state that he believed that animal species would change over time. Tusi contributed many texts to a philosophical topic.
Among his philosophical works was his disagreement with the philosopher Avicenna. His well-known philosophical work is Akhlaq-i nasiri or Nasirean Ethics in English.
Within this work, he discusses and compares the teachings of Islam with the values of Aristotle and Plato. Tusi's book became a well-known work in the Islamic world, especially in India and Persia. Tusi's work also had an impact on Shi'ite Islamic teaching.
His book Targid, also called Catharsis, is an important figure in Shi'ite theology. He also offered five works on the subject of logic which were highly esteemed by the people of his day and gained fame in the Islamic world.CONTINUE
