Beiträge zur Verbraucherforschung (Reihe in 2 Bänden)
Aus Band 1: Die Aufmerksamkeit der Öffentlichkeit wurde lange durch die Privatsphäre in sozialen Netzwerken und das Tracking der Online-Werbewirtschaft gebunden, weil dies die sichtbare Seite des Verbraucherdatenschutzes ist. Die Beiträge des ersten Bandes der "Beiträge zur Verbraucherforschung" rücken einen zukunftsweisenden Trend ins Blickfeld der interdisziplinären Verbraucherforschung und der verbraucherpolitischen Akteure: die Informatisierung des Alltags. Im Zentrum der Beiträge steht die Frage, ob und wie die Datensouveränität der Verbraucherinnen und Verbraucher unter den Bedingungen des Konsums im Internet, der Nutzung digitaler Dienste und in einer vernetzten Welt erhalten, wiederhergestellt oder gestärkt werden kann.

Mit Beiträgen von

Prof. Dr. Britta Böckmann, Prof. Dr. Rainer Böhme und Sebastian Luhn, MSc, Prof. Dr. Georg Borges und Dipl.-Jur. Sascha Adler, Prof. Dr. Ulrich Greveler, Prof. Dr. Artus Krohn-Grimberghe und Prof. Dr. Christoph Sorge.

Spirituality: A Working Scientific Hypothesis For Our Lives
Human being is one of the most complicated life form I have ever known. It is a being which can sacrifice its own life to protect another, but also at the same time can sacrifice another life for its own pleasure. While a majority of the population struggles through every day to fulfill basic needs like food, shelter and security, we have on the contrary some who display amazing acts of creation like music, dance, scientific innovation, paradigm shifting philosophical ideas, etc. which appears as a different dimension of living. Creativity is used for inspiring, transforming and empowering fellow humans & also at the same time, to create weapons of mass destruction. No other life forms I have noticed have ever exhibited such a level of contradiction. It is so baffling, and has always made me wonder, what is all this about? Who am I? What is life? What am I doing here? Is there a purpose to my existence?

All of us have encountered these questions during some point in our lives. And yet very few of us pursue the answers. Through this book, I am going to share with you the reason why these questions became so important in my life, how did I set out to find the answers, how it has transformed my life and why it is important for you to seek answers to these questions.

Science is an expression of the basic longing that a human being has to know and explore everything. Today we use scientific methodology to explore the world around us, and this has enabled and empowered us immensely in understanding many things and effectively uses them to make our lives more comfortable and convenient. But, when it comes to understanding the nature of life and of ourselves, we fail to employ a scientific methodology. Either people simply never pay any attention to this important aspect or usually they tend to have preconceived notions inherited from our family, society and the culture around us. Faith, religion, spirituality, etc are words usually associated to these preconceived notions and hasty conclusions about life.

Because of science’s unfortunate history in the hands of religion not so long ago and the very foundations of science was to release the intellectuals from the dogmas of religion, there is still a sense of dichotomy when we hear words like science and spirituality.

When we refer to something as scientific, we imply an active involvement of intelligence, exploration and reasoning. And what prevents us from using the same to answer these questions? What if we could use the same precision and clarity of scientific methodology to understand and explore ourselves?

Combining the facts from our modern sciences about the nature of our world, and by examining the nature of human beings, this book presents Spirituality as a working scientific hypothesis which brings into light the phenomenal complexity, intelligence and beauty of the process we call as life, and enable you to see the world and to see yourself from a new perspective, realizing the true nature and the immense potential of being a human.
