In the process of exploring the world, doubt is often the first step humans take towards truth. Doubt allows us to challenge existing concepts and drives humanity to continuously understand the world. However, doubt is merely the beginning of exploration; without the verification of practice, it ultimately remains at the level of speculation. The combination of doubt and practice is the dual wing that brings us closer to the truth. It is this complementary relationship that allows us to gradually touch the essence of the world.
Doubt is a beneficial mental state, a conscious reflection on existing knowledge and common sense. Doubt not only questions external facts but also includes an examination of the inner self. The essence of doubt is a spirit of curiosity and inquiry, refusing to stay on the surface phenomena and striving to dig deeper truths. Doubt is not merely denial; it is a further questioning of phenomena. Martin Luther initiated the Reformation because he doubted whether indulgences could truly absolve people of their sins, revealing the corruption of the church and the monetary transactions behind indulgences. This doubt prompted him to break free from the church's constraints and confront the truth. Newton's doubt about why apples fall to the ground opened his journey to explore universal gravitation. He did not stop at the phenomenon of the falling apple but, using the power of doubt, expanded it to the entire universe, ultimately revealing the existence of gravity.
It can be said that doubt frees people from being bound by established concepts, thus opening the door to new knowledge. This reflection on established facts forms the foundation of humanity's pursuit of truth. In daily life, doubt guides us to continuously examine the things around us, avoiding the trap of blind conformity. For example, our skepticism towards others' opinions and sources of information helps us form independent viewpoints. Doubt can lead us to discover gaps in our thinking, allowing us to continuously correct and improve our cognitive systems. However, doubt itself also has its limitations; remaining solely in the stage of doubt often fails to provide us with answers and can easily lead to endless speculation and self-doubt.
As philosophers say, "If one is perplexed but does not understand, the perplexity will never be resolved." Doubt is a positive exploratory attitude, but without the support and verification of practice, it is difficult to truly help us approach the truth. Relying solely on theoretical doubt, we find it hard to form a complete and accurate understanding of the world. Doubt lacking practical support often leads to conceptual confusion and unresolved perplexity. For instance, some blindly questioning science often lack factual basis and scientific methods, ultimately resulting in futile doubt. Some conspiracy theorists in society are immersed in doubt while neglecting the process of practice; they cannot discern the reasonableness of doubt and instead become burdened by it, falling into a state of skepticism about the world.
Practice is the key link that turns doubt into truth; it is the most important way to test doubt. Humanity's exploration of truth is not achieved overnight; many scientists have experienced countless setbacks and failures in the process of practice, but through experimentation, they continuously adjust their doubts and ultimately achieve breakthrough results. Yuan Longping, in his research on hybrid rice, initially proposed the idea of gene recombination, but during the experimental process, he realized that practical operations were far more complex than theoretical speculation. He conducted countless experiments and failures in the fields, continuously adjusting his experimental methods from cold resistance to yield, ultimately successfully developing high-yield hybrid rice, solving the food problem for hundreds of millions of people.
Doubt is the seed of thought, while practice is the soil that allows thoughts to blossom and bear fruit. The process of exploration is often arduous because, in practice, the problems brought by doubt require repeated experiments and corrections. In fields such as medicine, physics, and chemistry, the progress of scientists is built on countless experiments. For example, vaccine development is a typical case of the combination of doubt and practice. Scientists doubted the transmission mechanism of a specific virus, proposed different immune hypotheses, and after repeated testing and adjustments, ultimately verified effective vaccines in practice. Therefore, while doubt provides the direction for exploration, it is the steps of practice that truly lead to success. Without practice, doubt is like a tree without roots, difficult to survive.
The interaction between doubt and practice is the dual wing of human cognition; without either side, the flight of exploration cannot proceed smoothly. Many significant discoveries in the history of science have been achieved through the combined action of doubt and practice. Doubt is a force that breaks conventions, while practice is the process that materializes doubt. Scientific research relies not only on the inception of doubt but also on the verification of practice. Newton's doubt about gravity did not arise from thin air but was concluded based on his observations of various physical phenomena. Edison, in the process of inventing the light bulb, also verified his doubts about filament materials through countless experiments. Based on doubt, Edison repeatedly tested different materials and ultimately chose tungsten, achieving the first widely applicable incandescent bulb.
In our daily learning and work, doubt is equally important, but more importantly, is the reflection and verification of doubt. Many people may think that doubt means denying everything, but true doubt is a positive exploration aimed at finding answers to questions by posing deeper inquiries. The process of doubt needs to be based on seeking truth from facts, avoiding falling into an extreme state of doubting everything. Practice is the continuous feedback and verification in the process of doubt, thus finding the answer closest to the truth. Doubt and practice are two complementary parts; only with a balance of both can we approach the truth to the greatest extent.
In the development of science, the balance between doubt and practice has been followed by countless scientists. Excessive doubt can lead to decision-making delays, while a lack of doubt can cause one to blindly accept the status quo. Scientists find the source of problems through doubt and further refine theories through experiments, allowing science to continuously progress through incremental accumulation. In the field of medicine, vaccine development has been realized through the joint promotion of doubt and practice. Scientists question the transmission mechanisms of viruses and the responses of the human immune system, verifying the effectiveness of vaccines through practice, ultimately providing effective means for humanity to combat diseases.
Doubt guides people not to blindly trust authority or cling to conventions, while practice transforms doubt into constructive power. In the process of exploration, people need not only the inspiration of doubt but also the verification in practice to find answers closer to the truth. Scientists and inventors continuously explore in doubt and correct in practice, ultimately forming many far-reaching scientific discoveries and technological inventions. Therefore, doubt and practice can be said to be two important support points for human progress, driving the advancement of science and civilization.
In conclusion, we can understand the relationship between doubt and practice as follows: doubt is the starting point of exploration, while practice is the process of verification; both are indispensable. When facing a complex and intricate world, we need to maintain curiosity and doubt towards the unknown, while continuously verifying and advancing through practice, so that we can gradually approach the truth. As scientists say, "Science has no end," and the process of exploration is also endless. Doubt and practice are not temporary actions but are woven throughout the entire process of human development.
