This seminar will deal with 4 iomportant questions in the search for signs of life in outer space:
- How we form concepts of life in astrobiology, how we define and categorize things, and the relation between our concepts and our knowledge of the world:
- How we see similarities between things, and with inductive, analogical reasoning go from what we know to what we do not know, from the only example of life here on Earth, to possible extraterrestrial
- How we interpret what our senses convey in our search for biosignatures
- How we, as interpreters, establish connections between things, between the expression (the biosignature) and the content (the living organism)
In all, it is about how we get access to the world, and how we interpret and understand it, for achieving a well-grounded knowledge about the living Universe.
