 He believed that all changes are an illusion.
 There is only one reality, it is finite, uniform,
motionless, fixed and can be understood only through
reason.
 Knowledge is attained only through rational thought
because sensory experience provides only illusion.He
supported it with logic. Zeno who was his disciple, used
logical arguments to show that motion was an illusion.

found in number and in numerical relationships.
Mathematical Principles: He and his followers applied mathematical
principles to almost every aspect of human existence, creating a great muddle
of religious mysticism, music, mathematics, medicine and cosmology.

permanent and intellectually knowable and the other part is empirical
,changing, and known through senses. His philosophy provides one of the first
clear cut mind-body dualisms in the history of western thoughts
