The mind evolves to meet the challenges of existence.

The dead are never really gone, they just change form.

The beauty of physics lies in its ability to reveal the underlying simplicity of the complex universe.

The concept of purpose has no place in a scientific account of behavior.

The brave may not live forever, but the cautious do not live at all.

你是不是很烦躁，我的朋友？你是不是躺着也在担心？好了，不要担心，我在这里，我会在这里支持你的。一切都很正常，世界会变得和平的，饥荒会消失的，明天太阳依然会升起。
