All opinions, on any matter whatsoever, are shaped by the day and the culture in which they form.
That said, science is unique in human endeavor in that it actively works to remove blinders caused by that effect. Other endeavors, such as politics or religion, seem to glory in them.
It's the belief that slight, insurmountable cultural bias demolishes the truth in science or the value in modernity that is the basis of luddism.
To the extent that it's true to say science is shaped by the day and culture in which [it forms], is to make an interesting but ultimately meaningless observation. No one is capable of working outside his time and place. On the other hand, if "day and culture" were able to distort science, why does science originating in, say, pre-Victorian England, still work in post-Mao China?
The hubris of scientists is to claim that the scientific method is the only way we can know anything. This puts them in the unique position of claiming the right to say which questions are meaningful.
