From the Introduction: "In the early Christian centuries thousands turned to the Bible, as drowning men to a life buoy, because it offered them the only way of escape from the intolerable social and moral ills that attended the death pangs of the old heathenism. Then came the Dark Ages, with their resurgent heathenism and barbarism, when the Bible was taken from the hands of the people. In the hour of a nation's deepest humiliation and moral depravity, John Wycliffe, with the aid of a devoted army of lay priests, gave back the Bible to the people, and in so doing laid the foundations for England's intellectual, political and moral greatness. The joy and inspiration of the Protestant Reformers was the rediscovery and popular interpretation of the Bible. In all the great forward movements of the modern centuries the Bible has played a central role. The ultimate basis of our magnificent modern scientific and material progress is the inspiration given to the human race by the Protestant Reformation."
Laughter: an Essay on the Meaning of the Comic
Laughter: an Essay on the Meaning of the Comic
Henri Bergson
¥8.09
According to Wikipedia: "In the idiosyncratic Laughter: An Essay on the Meaning of the Comic, Bergson develops a theory not of laughter itself, but of how laughter can be provoked (see his objection to Delage, published in the 23rd edition of the essay). He describes the process of laughter (refusing to give a conceptual definition which would not approach its reality), used in particular by comics and clowns, as the caricature of the mechanism nature of humans (habits, automatic acts, etc.), one of the two tendencies of life (degradation towards inert matter and mechanism, and continual creation of new forms). However, Bergson warns us that laughter’s criterion of what should be laughed at is not a moral criterion and that it can in fact cause serious damage to a person’s self-esteem.This essay made his opposition to the Cartesian theory of the animal-machine obvious."

" The illiterate of the future are not those who can’t read or write but those who cannot learn, unlearn, and relearn."- quote by Alvin TofflerWhat clearly he meant is that we need to learn and unlearn as we continue to stay updated with what that works and those that no longer works Much has changed since the baby boomers days ,including the path of staying ahead in today's digital age.To succeed from now , one must learn to accept the constant change to adaptation – continually unlearning old ‘rules’ and relearning new ones.That requires continually questioning assumptions about how things has changed , un-valid old paradigms, and ‘relearning’ what is now relevant to pursue in acquiring your wealth.This book is filled with excellent ideas and concepts of daily struggle to understand money science.There is a lot here in this book that can help an individual move toward financial freedom through understanding money and the mindset required to become wealthy, of which means you need to know what it is that separates the wealthy from the Not-so wealthy. What you need to know and identify with is what principles and what behavior the rich have , and that you need to relearn . Some of which , You have not taken action to Unlearn yet ,to stay Current and Get Ahead " Happiness that Money brings cannot last " ,With Money ,People cannot necessarily materialize everything , However without money many things cannot be done Accumulation of wealth with the pleasure to have comfort , luxuries , reputable status , financial influence, freedom and popularity are what money usually can help to achieve , its provides a centralized role in our lives , at a general necessity stage level as it helps to clothe and feed us ,to put a nice accommodation for stay and pay the bills. Money may not be everything, they may not even guarantee a happy life, but they are a pretty good basis to learn how to build happiness on ... for now I highly recommend this book to anyone who'd like to ignore the fluff available on the Internet and take action now.Now that being said, this book assumes you know about the basics like Cash Flow, budgeting, etc.It doesn't talk about investment mediums like stock market, bond, etc.And the best part is that unlike many books, this book tells you not to lead a frugal life

The Amen Vibration:Volume II
Richie Quirino
¥0.01
This book is for seekers of truth beyond the teachings of parents, churches, schools, and communities. Forty years in the making, it includes the physical, mental, emotional and spiritual aspects of living, from the seemingly obvious to the occult, from the boundless diversity of paths toward Divine understanding and the unification of it all. The unity of the universe as functions of light and sound is explained and demonstrated in many examples. Light and sound are part of the same continuum of vibrations; they are simply different frequencies, as are things we see and hear, as well as microwaves, infrared light, and so on. At the heart of this continuum is the sound of the universe, the primordial Word: the Om of the Taoists, Aum of the Hindus and Buddhists, Amen of the Christians, Hu of the Ecks or the religion of Light and Sound and Hum of the Tibetans. These phenomena are explored by the author, who has experienced the discovery of one’s self and place in the universe.
