I have never heard of “reist”. Is that a type-o?

Phenomenology or Phenoumenology?

Reism is the description of Kotarbinski’s position on what exists, namely, real objects. Brentano, was also a reist. However, he believed that the body and the soul existed.

I take Kotarbinski’s position, and go further to accept on physicalism (athat there is “nothing over and above” the physical, or that everything supervenes on the physical), materialism (matter is the fundamental substance in nature, and that all things, including mental states and consciousness, are results of material interactions) and empiricism (knowledge comes primarily from sensory experience).
