How can I know that democracy is the best political system one can have? It is not coming from expericence, but it stems from our primordial need to do good and be good. It does not depend on empirical knowledge. When someone researches something, then the thing researches is not to be memorised but must become part of you. What words are not enough is empirical knowledge. When I research something, see that something works this way, then word are not needed, but empirical knowledge is. My results are not for me to remember but those results just are, independent on my memory, while words do not exist – only in our mind. Thus one cannot say that socialism is better than capitalism or vica versa, because this can be conjecutured only empirically and is only hypothetically truthful.
