paragraph_text: Avicenna (980–1037)
  
  In early Islamic philosophy, Avicenna (Ibn Sina) defined truth in his work Kitab Al-Shifa The Book of Healing, Book I, Chapter 8, as:
  
  What corresponds in the mind to what is outside it.
  
  Avicenna elaborated on his definition of truth later in Book VIII, Chapter 6:
  
  The truth of a thing is the property of the being of each thing which has been established in it.
  
  This definition is but a rendering of the medieval Latin translation of the work by Simone van Riet. A modern translation of the original Arabic text states:
  
  Truth is also said of the veridical belief in the existence.
