I want to start learning OpenGL with a book I have since a long time ago (Beginning openGL Game Programming) and it uses OpenGL 1.5 so my question is, should I learn OpenGL using this book and then learn a higher version? or should I start learning a higher version at once? are the same core concepts applied to higher versions?

"What should I learn" questions are really subjective based on your specific needs. They're also now explicitly off topic given the faq. – Tetrad Mar 11 '13 at 17:08
I just want to be able to learn more about 3D graphics and experiment a little with OpenGL. – Theil Mar 11 '13 at 18:35

No. Modern OpenGL and OpenGL 1.5 have very little in common. It's better to learn the modern OpenGL directly. Here is a good online tutorial for that: Learning Modern 3D Graphics Programming.

-1 While popular, this answer is just opinion. Some parts of them have very little in common, but other parts are pretty familiar. There's nothing backing up "It's better to learn...". – Byte56 Mar 11 '13 at 15:11
