If knowledge did not evolve, then according to what was once "accepted knowledge", the Earth would still be flat. However, this evolution was only possible because of the inherently flawed means by which humans acquired this so-called knowledge. The statement we will address throughout this essay – “What is accepted as knowledge today is sometimes rejected tomorrow” – has a key word: ; "accepted." When people accept something as knowledge based on unreliable principles, then it is bound to be rejected tomorrow. Because of the imperfect ways of knowing, our knowledge is also imperfect and therefore must always be questioned to ensure that it is accurate and reflective of the objective world. Various disciplines – science and history – and the knowledge claims associated with them will be examined closely throughout this essay to determine whether knowledge should in fact be discarded. What is knowledge? According to the scientific method, knowledge must be empirical in nature, measurable and reproducible through experimentation. Another common definition is that “knowledge represents our best understanding at a given time.” Looking at this well-known statement from an anonymous author, we can approach it from a linguistic perspective and focus on the part that says "at some point." This definition implies that knowledge is limited by time. However, when it comes to the idea that humans are imperfect, we generally claim things as knowledge that should not be considered as such. A good example of this would be the notion of God. For some people, God exists. But if we base this “knowledge” on the scientific method, it is not considered knowledge. We cannot carry out an experiment that can be repeated with the same result... middle of paper ... They built on the Christianity that once existed and molded it into their own beliefs - they didn't happy to do it. throw it away and create a new religion. Changes in Christian standards have occurred because of culture. So why are we in this constant race to change and modify everything we have? Well, everything around us can be questioned. The future challenges us. Rather than thinking about what we can do to improve our lives in a few hours, we think about what we can do to improve the world in 10 years – with the future based on human needs. Human behavior today reflects our actions yesterday. Almost everyone is now subject to denial which leads to improvement. This constant reminder and need to improve is what fuels the human race. We often find it easy to prove something is wrong, but our biggest obstacle is proving what is right..
