Metaphysics
- BeingWhat does it mean for something to be, and what is most real?
- FormWhat makes a thing the kind of thing it is: an intelligible pattern, an indwelling principle, or a structure imposed by the mind?
- InfinityWhat does it mean to be without limit, and can the infinite exist in being, in quantity, or in the world?
- EternityIs eternity merely time without end, or a wholly different mode of being, existence outside time altogether?
- One and ManyIs reality ultimately one or many, and how do unity and plurality hang together?
- MatterWhat is matter, the stuff of the physical world, and how does it relate to form, mind, and change?
- TimeWhat is time: a feature of the world, a form of the mind, or the measure of motion?
- SpaceIs space a thing in itself, a property of bodies, or a form of the mind?
- WorldWhat is the universe, and how does it stand in relation to God and to man?
- Same and OtherWhat makes things the same, and what makes them different?
