ABSTRACT
Basic knowledge is like the foundation of a large building. Everything else in the building depends on it in order to stand tall. The foundation is as basic as it gets within that building. The foundation could stand without the superstructure; the superstructure could not stand without the foundation. The most usual antiskeptical reaction to the regress argument is foundationalism. It says that not all justification is inferential. Equally, not all knowledge is inferential. Foundationalists often try to base all empirical knowledge, at any rate, on knowledge of appearances. Knowledge of what world appear to inhabit is the foundation for all of beliefs about what world do inhabit. Even a belief that inhabit a real world at all would be based on apparent sensings of such a world.
