Epistemology is the study of knowledge. By what conduit do we know what we know?

To have real knowledge, one must understand the essence of things and not only their manifestations.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.

Epistemology has always been affected by technologies like the telescope and the microscope, things that have created a radical shift in how we sense physical reality.

The ultimate aim of all science to penetrate the unknown. Do you realize we know less about the earth we live on than about the stars and the galaxies of outer space? The greatest mystery is right here, right under our feet.

The remarkable position in which we find ourselves is that we don't actually know what we actually know.

Knowledge of the self is the mother of all knowledge. So it is incumbent on me to know my self, to know it completely, to know its minutiae, its characteristics, its subtleties, and its very atoms.

Exploring the unknown requires tolerating uncertainty.

To attempt this would be like seeing without eyes or directing the gaze of knowledge behind one's own eye. Modern science can acknowledge no other than this epistemological stand-point.

Knowledge is what we get when an observer, preferably a scientifically trained observer, provides us with a copy of reality that we can all recognize.
