This/Husserl: initially includes the listener in the area of the speaker - This/Chi: can be explained without referring to "I".
Chisholm "I": defined without demonstratives, only by direct attribution (self-attribution) - "I" lacks the "speaker meaning": "I" usually has no meaning for oneself.
Analogy: "You" only term without listener meaning (recipient meaning)
Demonstrative/This/I/Kaplan: "I" only directly referential demonstrative, regardless of the opportunity.
Here/Demonstrative/Room/Chisholm: does not include an identification of the location - "It's cold here" with misconception about where one actually is, is possible - no opinion as to where one is - Location/Chisholm: things like planets, cities etc.: parts of properties and rooms - no absolute theory of space.
Now/Demonstrative/Chisholm: does not single out a time (not assumed by Russell, either) - the now maintains the connection to the present, the present loses it - E.g. three days ago he said that it was going to rain now.
