Spinoza and Taoism are the way to go for humans to lead a fulfilling life and be true to their nature.
If you want a philosophy book that explains humanity clearly and all the problems humans face, this is almost certainly the book for you. Of course, people who appreciate cats and understand a little about the mentality of felines will appreciate this book too.
Cats are true to their nature and don’t change, they don’t worry about happiness, they’re content with their life and know how to live it. They’re unburdened by anxiety and self-consciousness and can adapt to crises and transformations as they’re done down the centuries, since they domesticated themselves when humans became sedentary. They play with us when it suits them and may even grow to like us.
We can learn a lot from those kitties that have captured our imagination.
