The human mind treats a new idea the same way the body treats a strange protein; it rejects it.
[Sir Peter Medawar]

If you find a girl who reads, keep her close. When you find her up at 2 AM clutching a book to her chest and weeping, make her a cup of tea and hold her. You may lose her for a couple of hours but she will always come back to you. She'll talk as if the characters in the book are real, because for a while, they always are. Date a girl who reads because you deserve it. You deserve a girl who can give you the most colourful life imaginable.
High level concepts such as intentions, meanings, thoughts, and so on, which we associate only with minds, must have had evolutionary precursors in a more or less gradual sequence. The problem is that we do not have a clear concept of what the simplest "intention", "meaning", or "thought"” might look like. This is because psychology has traditionally been defined by only highly evolved "mental" activity, so that even though we study brains at the cellular or even molecular levels, there is the tacit belief that no real psychology can exist at a simple level.
