Who Am I? And If So, How Many?: Answering life’s questions via self cognition
The author does not represent specific ideas of any school or people, but multiple achievements in many sectors. And what perspective is right, what is wrong? What is the most persuasible? I think that is not his intention. He only wants to give us a multi-perspective point of view.
Diverse point of views
When studying science, considering in many perspectives is important. Any point of view seams to be reasonable in this perspective possibly seeming reasonable in the opposite perspective also. At that time, you might think: “Believing totally, and stop continuing from the first point of view is impatient and somehow stupid.” Then you would know that if two philosophers with definitely opposite/anti-each-other opinions are equally smart and respectful. And in many cases, they are both reasonable, too.
If you find something which is reasonable, acceptable and sounds good, that is great. But such finding should not stop you from finding different ideas, should not stop you in your path to truths. You need to study supporting, similar, and opposite ideas to strengthen your thoughts, to correct your doubts, and to justify your conclusion. Truth is not unique, it survives.
More generally, looking at other sciences, for example in this book is psychology and biology, is recommended. To many questions, philosophy alone is one-sided. Philosophy should not and never is the single source of truth.
Stopping thinking, concreting ideas is a dead end. Philosophy itself has not ended.
Note from the book
You think “To be is to do”
Or “To do is to be”
Oh, that might be “Do be do be do”
