The obvious answer to that question is – yes, you can think too much. If all you do is think and not act, you accomplish nothing. On the other hand, in order to live life intentionally, you do have to have intention and that requires thinking.
What is needed is balance. As a Humanist my preference is to engage in quality thinking rather than the quantity of thinking I do. I want to be able to think well and also to enjoy my life for what it is. But again, that’s a choice that required me to think that I wanted to make that choice.
Thinking, like any other skill, requires practice to do well. You have to practice thinking critically in order to be able to think well. And that requires you to put in time learning, educating yourself and practing logic, skepticism, skepticism of your skepticism and so forth.
There is a reason why learning to think critically is considered an essential element of living a fulfilling, ethical, natural life. As Socrates said, “The unexamined life is not worth living.” Thinking is essential. Here is a video all about the importance of thinking from a Humanist perspective.
The Spiritual Naturalist Society works to spread awareness of spiritual naturalism as a way of life, develop its thought and practice, and help bring together like-minded practitioners in fellowship.
