I believe that ideas are not formed innately in the mind. From the moment we are born, we are surrounded by impressions of the world. Inspired by our desire for self-discovery, we develop concepts that derive from everyday life experiences. Not only can we create these ideas from external events, but they can also be created internally. However, the emotions we feel in different contexts such as love, anger, sadness, even the general way we feel towards someone, are based on interactions. For example, when a child tastes vegetables for the first time and discovers that he doesn't like them. This child could not have had any idea of ​​what the vegetable tasted like without first experimenting with it. David Hume believes in the copy principle, according to which ideas arise from impressions. According to Hume we cannot form ideas without impressions. Ideas themselves are simply less vivid impressions or composite impressions formed by the mind. Even so, there was one case where Hume's copying principle was called into question. In the case of the man who goes blind after thirty years, who has never had the impression of a certain shade of blue, he may be able to have an idea of ​​what it would be like. At the time, Hume didn't think there was anything significant that could go against this idea of ​​the copying principle. Nancy Kendrick uses this missing shade of blue to show that this counterexample actually provides Hume with an empiricist and non-nativist example of the priority of an idea over experience and, thus, revitalizes, rather than diminishes, his most key empiricist purposes . Furthermore, Kendrick also uses John Lock as a reference to support Hume's claims in rejecting innate ideas and in turn understanding the mi...... middle of paper ...... having no experiential counterpart (Kendrick, 2009). . The concept of ideas, which do not come from the corresponding impressions, makes the lack of blue tones a slight exception in a way, but there is not enough reason to delve into it. Hume suggests that the idea of ​​the missing shadow may arise from the imagination. Kendrick takes a hint from the Treatise to argue for the lack of the shade of blue; the imagination, when set upon any line of thought, is apt to continue, even when its object disappoints it, and like a galley set in motion by oars, continues its course without any fresh impulse. Hume's Copy Principle is intertwined with many aspects of understanding the individual's understanding. The impressions we receive throughout our lives are the driving force behind the ideas we create. Although not all ideas may be based on the same impression, it comes from our daily experiences.
