The discovery of flint marks a big step towards civilization in human society. Similarly, the discovery of truth also marks the progress of human society. As a middle school student, what kind of enlightenment will you get if you chew this famous saying of Marx seriously?

First of all, it must be "flint", otherwise, no matter how powerful it is, it will never "emit" a spark. This is like the truth that "hens can hatch chickens from eggs, but they can't hatch chickens from stones". Secondly, although it is "flint", it must be "beaten" to be "brilliant". This is the same as the truth that "the blade comes from sharpening, and the plum blossom fragrance comes from bitter cold".

Therefore, this famous saying of Marx contains at least two well-known philosophical truths. But it is not abstract, but vivid, easy to understand and profound. Such a proposition is not difficult for middle school students, it can arouse their cordial memories and enrich their associations, is suitable for vertical and horizontal extension, and can effectively test the knowledge storage and understanding depth.

Here, the proposer's intention is obvious: I hope the students can make bold innovations, seriously understand the information implied in Marx's famous saying, and express newer and deeper philosophy through their own articles. For example, lamenting the fate of a "flint" abandoned because no one recognized it, and then regretting the burial of talents and urgently calling for the emergence of "Bole"; For example, express your own views on the gradualism of truth, and thus put forward that the object of "knocking harder" must be updated accordingly, and the knocking methods should be updated accordingly.
