Relationships between predicates can be stated using logical connectives. Consider, for example, the first-order formula "if a is a philosopher, then a is a ...
Predicate Logic: Relational Predicates. Predicate Logic: Multiple Quantifiers. Order of quantifiers. If an expression contains more than one quantifier, does it matter in what order they appear? If it does matter, which quantifier goes first and when? When the quantifiers are of the same type, then their order does not matter. For example:
And again, the stress on 'relational' in 'relational logic' is typically meant to indicate that we don't (just) consider unary predicates. Also, theoretically there is a big difference between logics that consider only unary predicates, and logics that use any kind of predicates: the former are decidable, whereas the latter are not.
If these lecture notes from Stanford are about what you call "relational logic" then it is just another name for predicate calculus. There used to be something else called relational logic (or logic of relatives) developed by De Morgan and Peirce in 19th century (logic of intensional predicates in modern terms) but it is a rather niche subject today.
Relational Logic is an alternative to Propositional Logic that includes some linguistic features, viz. constants and variables and quantifiers. In Relational ...
