We can point out firstly that we study these perennial problems through the study of history, a discipline in which we must specialise because of the immense scope of the subject, it is therefore possible to investigate these problems through the Mikra. However, this would not establish a claim that the Mikra is somehow relevant to all peoples. We can also argue secondly, that the Mikra is part of the totality of history, and that in this sense it has an enduring claim. This sort of claim can be made for any extract of ancient history, however, so although it justifies the claim that the Mikra has historical relevance it cannot go beyond that to universal relevance. There is also the problem that in the 'modern scientific age' textbooks quickly become obsolete.
Science replaces knowledge very quickly.
Scientific textbooks are often disposable after only a few years. We really cannot do this, for to argue that it is as disposable as a scientific textbook is to confuse two different kinds of literature. Scientific literature is, as scientists admit, theory, and theory is only useful as far as it helps to solve problems. Once a better theory is produced old theories are disposed of. Similarly, accounts of mankind's adventures are unique, for no one can ever recreate the unique experience of adventures of another.
