Knowledge is only personal {subjectivism} {idealism}. For example, colors are visual mental states or properties. Brain opponent processes cause qualitative color similarities, with no correspondence to physical properties. Neural properties that explain qualitative relations among perceived colors can differ from perceived colors themselves. People do not necessarily experience such similarities, or they are not essential, so they differ from color itself. How do brains perceive mental qualitative visual properties as mind-independent object properties? Do mental qualitative properties or states have functions?
Sense data, secondary qualities, primary qualities, space-time universals, and natural laws can be part of absolute self and so be universal and objective, but may be only illusions.
