what's the meaening of sensibilia in philosophy?

Answer 1

'Sensibilia' is equivalent to 'sense-data'.

It is the immediate effects of our sense organs in our mind, the irreducible qualities of an object that we get from perception. A much beaten-to-death example is the perception of a red color patch. For it seems arguable that we do not perceive objects, for the large part, directly, but form judgments about the way things are on the basis of the sense-data immediately available-- such as seeing the top of what-seems-like a table and inferring the rest of a solid object.
