The following article is a reflection on the value of peace, a term often attributes to the absence of war or the lack of violence, conflict, suppression or, in short, phenomena considerer opposite to peace. But, is this really how peace should be defined? It is a fact that peace, be it personal inner peace or peace within a society, is constantly threatened, attacked, violated, and destroyed by a variation of causes: the failure to keep a promise, the breach of (...) a contract, obtained by illegitimate means, economical ambitions, diverse geo-political strategies, anarchy, social pressure, the lack of understanding on an interpersonal level, a family crisis, immaturity, unemployment, acts of injustice, poverty, the failure to adapt, discrimination, migration, terrorism, arms trafficking, civil wars, the threat of a world war and the usage of weapons of mass destruction, etc.; factors that take away peace, among men and women, societies, and entire countries. But…what is peace? Why do we struggle so much to obtain it? Why is it so appreciated by the majority mankind? Why have humanists, philosophers, politicians, civil right organizations, and men of good will in general dealt with this topic in such an extended manner? Why it has written so much about peace? Why peace is so fragile? These are some of the questions that I will try to answer in this contribution, using some of the texts of St. Augustine, Hobbes, Rousseau, Kant, and Hegel as reference.

This research was carried out in order to verify by simulation Mendel’s laws and seek for the clarification, from the author’s point of view, the Mendel-Fisher controversy. It was demonstrated from: the experimental procedure and the first two steps of the Hardy-Weinberg law, that the null hypothesis in such experiments is absolutely and undeniably true. Consequently, repeating hybridizing experiments as those showed by Mendel, it makes sense to expect a highly coincidence between the observed and the expected cell frequencies. By (...) simulation, 30 random samples were generated with size equal to the number of observations reported by Mendel for his single trait trial, in this case, seed shape; assuming complete dominance, with genes A and a; likewise, it was simulated the results for the experiment with two traits, segregating in separate chromosomes, in this case seed shape, as before, and albumen color, with genes B and b, both loci with complete dominance. In the case of a single trait, the data only showed evidence for rejecting the null hypothesis (Ho ) in 1/30 samples, with (P<0.05). In the case of the 30 samples of the two traits experiment, (Ho ) was rejected only on 3/30 times, when it was set a = 0.05. In both simulations there was a high correspondence between the observed and expected cell frequencies, which is simply due to the fact that (Ho ) is true, and under these conditions, that is what would to expect. It was concluded, that Mendel had no reason to manipulate his data in order to make them to coincide with his beliefs. Therefore, in experiment with a single trait, and in experiments with two traits assuming complete dominance, segregation ratios are 3:1; and 9:3:3:1, respectively. Consequently, Mendel’s laws, under the conditions as were described are absolutely valid and universal. (shrink)
