I think both of you are correct, in that:

- Object are tangible things capable of processing -> composed of methods
Thus an object isn't an entity that aggregate other entities (method objects). It's a closed, encapsulated, independent thing.

However, it'd make sense to treat method as first-class objects. A method is only a procedure bound to an instance. In fact, Ruby allows you to do that:

m = my_object.method( :a_method ) # returns a Method object bound to my_object
m.call
