Critical judgment of work in a given field has little value unless it comes from someone who is an expert in that field. Here the speaker claims that critical analysis cannot be accomplished unless one is an expert in the subject. However, the fact that critical analysis cannot be conducted without someone being an expert in a field does not mean that critical analysis has no value. Considering the various fields of study, there are many examples where critical analysis has played a significant role in advancing knowledge and understanding of a topic. In fact, critical analysis has been vital to most scientific theories, theories in philosophy, and theories in the humanities. Without the critical analysis of these subjects, there would not have been any progress made. Critical analysis, therefore, has value in fields other than science

The field of science is a prime example of where critical analysis has been vital to understanding. Many of the theories that were developed in the scientific revolution were the result of critical analysis. Before scientists could advance their theories, they had to consider alternative hypotheses to the ones they were proposing. In many cases, scientists had to challenge others’ ideas, and could only do so if they possessed the relevant knowledge. In many cases, critical analysis led scientists to develop theories that were previously unthought of, such as the theories of Einstein and Darwin. Critical analysis has also allowed scientists to improve their theories, such as Newton’s theory of time and Hooke’s law of elasticity. Without critical analysis of scientific theories, scientists would not have been able to perfect the theories they have today

Critical analysis has also been vital to theories of philosophy and the humanities. In philosophy, philosophers have used critical analysis to compare different philosophical theories in order to understand their similarities and differences. Critical analysis has also allowed philosophers to come up with new ideas, such as the concept of relativism. Additionally, critical analysis has allowed philosophers to debunk faulty theories that had previously been accepted as fact, such as the idea that the Earth was the center of the universe. Critical analysis has also allowed philosophers to postulate new theories. For example, the philosophy of existentialism was first proposed by Søren Kierkegaard through a series of critical analyses of the works of philosophers such as Plato, Socrates, Immanuel Kant, Friedrich Nietzsche, and Martin Heidegger. In the humanities, critical analysis has allowed historians to improve their understanding of previous civilizations and periods, and of historical concepts, such as the nature of God

Critical analysis has also played a critical role in the development of technology. Engineers and inventors have used critical analysis to develop new technologies, such as computers, cell phones, and the Internet. Computer engineers, for example, have used critical analysis to devise operating systems, hardware, and software. Critical analysis has also allowed them to identify weaknesses in existing technologies. Engineers and designers have used critical analysis to perfect various devices, such as the space shuttle and the Spitfire airplane. Critical analysis has also allowed designers to improve the usability of products. Critical analysis has also helped to develop new technologies. For example, critical analysis of quantum field theory has led to the development of string theory, which is a theory of quantum gravity, and the theory of superstring theory, which is a theory of quantum gravity, supersymmetry, and gravity

In conclusion, critical analysis is of value in all fields, including science, philosophy and the humanities. It has helped scientists develop theories, philosophers come up with new ideas, and designers improve products. Critical analysis has also proved to be important in the development of technology. Therefore, even though critical analysis cannot be conducted without someone being an expert in a field, it does not mean that critical analysis has no value.
