Deep Thoughts Quotes
According to psychologist Keith Stanovich, it may be the media’s overuse of words like “breakthrough” that leads the public to imagine that science is constantly proving everything it thought was true to be false. While there are such famous cases as the theory of relativity that required a complete reconceptualization, these are extreme exceptions. Knowledge in science is gained by a gradual synthesis of information from different experiments by various researchers across different branches of science; it is more like a climb than a leap. Theories vary in the extent to which they have been tested and verified, as well as their acceptance in the scientific community. Therefore, scientists adhering to proper scientific approaches will doubt themselves even once they possess the truth.
Modern science is distinct in its approach and successful in its results, so it now defines what science is in the strictest sense of the term. Science in its original sense was a word for a type of knowledge, rather than a specialized word for the pursuit of such knowledge. In particular, it was the type of knowledge that people can communicate to each other and share. For example, knowledge about the working of natural things was gathered long before recorded history and led to the development of complex abstract thought. However, no consistent conscious distinction was made between knowledge of such things, which are true in every community, and other types of communal knowledge, such as mythologies and legal systems.
Metallurgy was known in prehistory, and the Vinča culture was the earliest known producer of bronze-like alloys. It is thought that early experimentation with heating and mixing of substances over time developed into alchemy. There is disagreement, however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence. Disciplines that use existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences. The nature of reality used to be in the realm of philosophy or even religion and spirituality, but sciences have started staking a claim to it.
In the last couple of decades, cognitive neuroscience has begun to understand the true nature of reality as a representation of our sensory inputs. It is a representation that maximizes our chance of survival. Once this scientific understanding of reality percolates to other modern sciences , what is explored in this book will become part of our basic knowledge. We will see clearly the role of sensing and perception in the theories of physics. New scientific knowledge rarely results in vast changes in our understanding.
