This book is a wonderful introduction to philosophy. I read it from the perspective of one with an interest in the field, who aspires to study a course involving philosophy at university. To that end, I found this book brilliant. It manages to serve as an introduction (or rather, invitation) to philosophy that both invokes a sense of interest for the subject, and is detailed and rigorous enough to make you think to understand the book’s content.
I think one really needs to understand what the book covers. Invitation to Philosophy is not a whistle-stop tour of the whole field of philosophy, instead it only focuses on a few fundamental concerns of the subject: logic, knowledge of inner and outer worlds, the self, morality and free will vs determinism. Instead of covering each branch of philosophy individually, Hollis brings in relevant aspects of each when tackling these questions, and thus weaves a coherent argument that requires careful reading to stay on top of, but is very informative. Perhaps the subject is best presented this way – in its argumentation.
If you are in a similar situation to me, reading this in preparation for higher education or similar, I recommend reading at a pace slow enough to follow the book’s arguments, and to make notes afterwards; this helped me organise my own thoughts and consolidate my learnings.
This book is less well-known than many other introductory books to philosophy, but it is a great place to start. I would wholly recommend it.
