Since the beginning of my unceasing activity as a teacher determined in providing students and biomedical professionals a clear conception of an abstract discipline, usually considered inaccessible due to the mathematical basis that supports it, I caressed the project of editing a few pages in which, without a single equation, I would be able to convey the philosophical contents of the Statistical Method as a irreplaceable weapon in the struggle of the researcher against Life´s variability. Many years have had pass until this project could acquire the form of reality that today, with the humility of whom presents a small job, but well meditated, I submit to the consideration of those that with it will be able, by means of a purely conceptual knowledge of the Method, to love Biostatistics a little more.
