Coming from a natural science viewpoint I find that logical positivism is much more important for scientific research than is critical theory. I've read the critics/flaws of logical positivism and while I think some of them are valid (e.g. Quine) these are only minor deficiencies. On the other hand I have not found anything critical theory has ever provided for the advancement of scientific knowledge. Can somebody point to discoveries / methodologies put forward by proponents of critical theory which are clearly superior to logical positivism. From my current viewpoint it seems that logical positivism is the school of thought which yielded all the progress in the natural science and technology today while critical theory is more of a programmatic ideology.
