Sciences there especially if we talked about social sciences (the topic of this thread), yes of course since they are founded on a pure materialistic atheistic basis. Which is 180 degree opposite to the Islamic view as you know very well.
Social sciences, sometimes referred to as the "soft" sciences (as opposed to physics, mathematics and so on) are to a lesser degree based on hard evidence, and there is usually more room for interpretation. That being said you have to admit that the "western" way of looking at the world has been highly successful, bot on a global as well as on a local level. Secularism has indeed had its perks and in my own country we all enjoy the fact that, for instance, religious freedom is a given. That includes quite a few Iranians who, if we had had the same idea about this topic as Iran, would not have been able to practice the religion of their choice.
Since the West dominated other nations which are defeated on the moral and intellectual levels (in addition to the military, political and economic aspects), you and many others thought that there is only one science, one truth and everything the West says is the truth that the entire world must submit to and says ameen.
And as long as the proverb "might makes right" rings true, that is unlikely to change. No matter what Ahmadinejad would like his people to think there is no Muslim nation, or nations for that matter, that is even remotely a threat, with regards to military power, to neither Europe, nor the US. And they should be glad that they are not. If they were, and we actually took his speeches seriously, things might have gone quite differently for them.
Some people worry about Iran getting a hold of nuclear weapons, but personally I'm not all that concerned. Unless Ahmadinejad is suicidal, actually using them against anyone is a very very remote possibility and would only lead to Iran being completely wiped from the planet.
And that is why the Iranian concern is worthy of thanks yet I think they chose the wrong means as I said before. The problem of Muslims now (like the other nations) is that they lost the ability to criticize and choose so everything coming from the West which indeed look shiny and tasty from outside but actually is poisoned, became the standard.
While it would be arrogant (and highly inaccurate) of me to proclaim that everything that comes from the West is golden, one has to realized that the modern secularized societies and principles upheld in the West do indeed make for better functioning environments for its people. This is something that the Muslim countries would do well to take note of. Whether you like it or not, our way works from a humanitarian, educational, economic, welfare and personal freedom point of view. And it works better than the Iranian, Saudi Arabian or Afghan way. A lot better.
(I am prepared to back these statements up with statistics if need be.)
So what we really need is to promote the ability to criticize and make conscious informed choices, but as I said restriction of these sciences all together is not the solution.
When an Iranian citizen can freely and openly reject Islam and criticise the government without fear of being killed or imprisoned you will know that we have made some progress in the right direction.
