Life the Universe and Everything - general chat for the philosophically inclined

Another great meeting into the early hours of last Sunday after Melbourne Existentialists Society meeting - Existentialists meetup =
https://4142298.xyz/existentialist-society/?eventOrigin=event_home_page
----------------------------------------------------------------------------------------------------
Some of the many topics discussed after the Existentialists, in the subsequent "Street Philosophy" meeting were Idealism v Realism - ABSOLUTE TRUTH - What does that mean ? does it exist ?
Things we may discuss = Ontology, how equiped are we to fathom the nature of things? HARD PROBLEM OF CONSCIOUSNESS: WHERE DOES CONSCIOUSNESS ARISE?: DOES DNA TRANSLATE TO BEHAVIOUR?, IF SO HOW - definition of rationality - origins of "value" - precision of mathematics - concept of infinity.
Have been having some great flowing discussion as topics arise following conclusion of existentialists meeting, Melbourne, Australia. Thanks to all attendees.
General chat for the philosophically inclined about whatever comes up,
suggest topics as suits you or -
- possible topics
Information
- where is the information in an un opened book, does it exist when unobserved?
Reason
- what is the definition of reason
does it exist in physical laws, i.e if we can we say "the rock fell because of gravity" how is this different to "what is the reason she chose pepsi max instead of coke zero?
Validity of evolutionary physchology
- what evidence is there for evolutionarily selected behaviour, given that we cannot observe the history of the emergence of neurological structures as we can observe evolutionarily selected anatomical changes?
