 Some philosophers take it to be obvious that if something is true, there must be something that makes it true, a truth-maker. Facts are truth-makers. Like sentences and thoughts, facts are taken to be complex objects. The constituents of (atomic) facts are not words or modes of presentation, but particulars and properties (see, for instance, Armstrong 1986: 85). The fact that Socrates is wise exists if, and only if Socrates is wise.
