How to understand, Russell s sentence Please comment on this sentence of Russell.

Very powerful question I think Russell means that we have an empirical understanding of light and matter before we know about them scientifically, that when we say light we don't care about the nature of its waves or particles, that we only think of the impression that light makes of our vision, and that he thinks that we have defined light or matter from our life experience long before we know the nature of it, and that it is inappropriate to redefine it again with science, or that the scientific definition does not encompass the full meaning of a substance.

Asami: The world that people perceive is not the same as the world in science.

Like: 1We see that the leaves are green because it absorbs most of the other light, and the remaining green light is transmitted to our eyes in the form of waves.

2.For example, in a dark room, a red light is used to hit a cyan wall, and the wall is still black, just because red and cyan are complementary colors, and absorb each other (you must know if you have studied art or photoshop).

This is the difference between philosophers and scientists, and for philosophy, it is usually good to correctly explain the "light" that people see in general and be able to understand and agree with it, and no matter whose philosophy it is, it contains a certain subjectivity. For scientists, it's about using their constructs, equations, or whatever, to explain the composition of "light", and it doesn't matter if you know what "wave" means. However, we should see from his words that Russell did not deny the truth of science, but indirectly expressed his own desire that "it is wrong for people to separate and oppose "science" and "philosophy", and that the two should be unified.

Russell's famous three quotes are as follows:
