The famous saying "Failure is the mother of success" contains a profound and clear philosophy. The philosophical principle it reveals is the law of the unity of opposites. That is to say, the opposites in things are both opposed to each other and interdependent. Moreover, under certain conditions, the opposites will transform into each other. Hence, there is a Western proverb: "The fruits of failure contain the seeds of success." But it is worth reminding that the most important thing is that we can learn from the results of failure and discover the seeds of success. If we only see failures but cannot inspire us or help us find ways and opportunities for success, then failure is ultimately a failure and will not help us. Therefore, when it comes to failure, one must have experience, the other must have wisdom, and the third must have the opportunity to start, all three are indispensable. On the other hand, there are people who have been engaged in scientific invention research for a lifetime, and after millions of failed experiments, there are still no major inventors, and there is no shortage of them! It can be seen that it is not enough to just know the principles of philosophy. There is still a long way to go before we can apply them in practice to make brilliant achievements.
