There are different areas of knowledge that can explain different things with different levels of uncertainty. The certainty of knowledge from natural sciences is higher as people have faith in scientists who have supported a theory through a lot of observation as they’ve noticed a pattern and many experiments with evidence to support their theory, and many others who have gotten the same results. When they get the same results people begin to believe it and “know” of it as being the truth. People trust them as they have a higher authority and can provide answers that the general can agree with. The certainty could be considered greater than religion as there is more evidence to support the scientific theories, but people can still “know” through religion because of their beliefs and their faith even if there is less evidence to support it. Another way of knowing is with history. People “know” as there is a lot of evidence and justification behind it. There is also technology helping us with understanding what has happened in the past, like fossils or photographs. We can not be certain of things that were in the past as there might not be an explanation or too much evidence behind it. People also have different perspectives and can view the things that have happened in different ways, so the knowledge about one thing that we hold may not all be the same. We can ‘know’ the same thing but may have different reasons to why we know them, some may have a stronger reasoning however not everyone can agree on the same thing and can have their own personal judgement. But we can not be “certain” about anything.
