Here is (more or less) the address that Richard Feynman, the noted physicist, gave at commencement for Cal Tech in 1974. It's a bit about science, but it's not at all "techy", and I think it's worth reading and considering.
The things to take away from it (for me) are:
1. Science is simply the way to understand the world, nothing more. Nothing magical there. Anyone can do science.
2. Good science is science that can be proved wrong. Bad (pseudo) science can never be proved wrong, because it's overly broad or untestable or whatever.
3. Science works best when it, and the people doing it, are nothing but honest. If your experiment disproved your theory, say so. Don't hide it. Even if it did work, identify the reasons you could be wrong.
4. There's nothing wrong with science (or knowledge) for its own sake.
