目的的概念在行为的科学解释中没有位置。
Read, read, read. Read everything — trash, classics, good and bad, and see how they do it. Just like a carpenter who works as an apprentice and studies the master. Read! You'll absorb it. Then write. If it's good, you'll find out. If it's not, throw it out of the window.
科学是关于后果的知识，以及一个事实对另一个事实的依赖。
"The best and most beautiful things in the world cannot be seen or even touched - they must be felt with the heart."
