ABSTRACT
Concrete objects (‘concreta’) are not, as you might expect, those that are mainly made of cement. In metaphysics, the concrete things include tables, chairs, mountains, cars, stars, you and me (although it does, also, include those things that are made mainly of cement). In other words, material objects are said to be concrete. However, other things are usually said to be concrete as well: if there are immaterial objects (ghosts, angels, souls, God, etc.) they, too, are concrete; events (such as Second World War or your lunch yesterday) are often labelled as being concrete; immanent universals are concrete; tropes are usually said to be concrete; and for those who believe in them, holes are concrete objects. Roughly, then, the things in space and time are concrete (with exceptions made for angels and God, which are not in space and time – but that is why we used the word ‘roughly’).
