Affordances are features of the environment
SupportiveArgument

#493
Affordances are directly perceived higher-order properties of things in the environment—eg water affords swimming and floating, foods afford eating etc. They're envrionmental factors that an organism directly "picks-up" in order to maintain itself.
Affordances aren't representations used as guides.
James Gibson (1977 & 1979)

The representational tradition is flawed☜Classical symbolic AI places too much emphasis on the role of representations in human intelligence. Acutal human thinking only becomes symbolic and representational when normal modes of cognition break down.☜EF597B

Affordances are just symbolic representations☜Affordances are nothing but internal representations whose symbolic character is concealed from consciousness. Acquiring affordances is a matter of encoding sensory stimuli as symbolic representations. ☜EF597B

Affordances are trivial☜Affordances are just another name for whatever it is in the environment that makes an organism respond as it does. But such a notion cant provide a substantial explanation of perception and adds nothing new to our knowledge of perception mechanism☜EF597B
