Red, 650 nanometer wavelength electromagnetic radiation, what's the difference?

I was intrigued by Husserl's concepts about Galileo and the "bifurcation" of the lifeworld from the "world" of science. Husserl suggests that the lifeworld is, on its most fundamental and real level, a world of perceptions and embodiment. He views Galileo's "mathematization" of the world as an attempt to perfect the sensory world, and Husserl thinks that this necessarily overlooks some aspects of the sensory world. Husserl called these qualities "plena", an example being the color of an object.

I don't think Husserl's opinions of Galileo and the science he is helping to establish are accurate, or that a "bifurcation" occurs between science and the lifeworld. I think that Husserl's concept that reality or the lifeworld is ultimately something we experience is wrong. In the end I think there is a reality external to the way we percieve it, and modern science is based on this. Human senses are very powerful and central to our interaction with the world, but they are also limited and imperfect. Science does not depend solely on what we can directly see, taste or touch, and as such can describe reality in a much more encompassing way. Human senses are also very subjective, people can perceive things differently in different situations. To say that the way we perceive reality is the way reality actually exists is absurd. Husserl's "plena" I think are equally ridiculous. Certainly there are aspects of the way we percieve things that are difficult to quantify or explain, but I think there is still a way to explain them. If something we experience is totally unrelateable, I think it is just one of the subjective experiences of the individual mind, and not actually descriptive of reality in any meaningful way.

Science has its limitations, of course. A lot of assumptions are made here and there, and some approximations and estimation. But I think it does an infinitely better job at desribing reality than human perception alone could. If anything, science has brought us closer to reality and understanding it, rather than splitting us from it as Husserl suggests. And as Ihde even points out, modern science has "perceptions" of its own with intrumentation of all sorts to detect and measure natural phenomena that no human could do alone.
