Historical truth, in a way, is part of a scientific truth as it requires observation and hypothesis. Though science is the most acceptable way of knowing truth, it can never prove anything without an object. Historical truth, however, does not require performing experiments over and over again. Instead, historians will look at documentical evidence, eye witness’ account and evidence from archaeology. This will sum up strong evidence of accuracy, while flawed evidence can be ignored. For gaps in the past without evidence, historians can interpret known facts and then make an approximate guess. This is not acceptable is scientific means, yet it has produced a record of past history. Though, sources can be unreliable due to the influence of propaganda and they might not be a full record.
Some people might argue that truth can also be known by using our current knowledge and certainty. These are moral truths. They cannot be observed or touched, thus cannot be proven scientifically. It all depends upon abstract reasoning, where conclusions are made using logic. It does not rely on observable evidence that might be lost or misinterpreted, but follows good reasons that is proven true to make conclusion. This, however, is not full proof as not every person will agree with the premises.
We can also argue that truth can be known from sacred writings (e.g. Bible and Qur’an) and personal experience. This is spiritual truth which cannot be proved empirically but is a belief accepted on faith. No proof is possible for this, yet it can answer many important things about lives and humans.
To conclude, science can indeed provides us proof to most truths, however, it is not the only way to reveal truth. Science is just a way to prove hypothesis using experiments. These experiments are yet unreliable as the theory might change when new thinking comes in. Therefore, science cannot provide us absolute truth. We can find evidences in history and sum them up to form historical truth. We can use logic to form abstract reasoning, which is moral truth. We can also quote sacred writings, and genuinely belief in God, spiritual truth is proven. There are various truths, and there are many ways to find out about them.
