The word pass is very close to the word weigh, to the act of putting something on the scales. One does not spend time well without knowing its weight, the meaning that each one is capable of adding to it. Not making good use of it is a cause of regret. Time is the element common to both the builders of life and to those who watch it pass by undisturbed. It is the most precious intangible value that enriches rich and poor alike.

As the hours go by, it is the product of those who make time have weight, not weight. It has weight to know how to differ, because like life itself, the truth, whatever it may be, must be constantly open to scrutiny, analysis, reflection, criticism of its ideological bases, and deep introspection of the ideals that shape it. Encountering the truth is an enlightened act, a libertarian deed. For this very reason, this book should be read with a keen and inquisitive mind, willing to be shaken and to disagree with the author. He encourages such frank and open dialogue. Not to do so with a book made for thinking is unnatural, a denial of
authentic reading. Resist being tamed and read it alertly, exploring between the lines, ready to see other horizons. Not to do so, underestimates these letters capable of sowing a watery uneasiness. But it is one thing to judge ideas and quite another to judge people; to commit this stumbling block is to disregard Christ Himself who said: "I judge no one" (John 8:15). (From the prologue written by Juan Francisco Altamirano, PhD).
