In order for someone to deal with philosophy it is not necessary to have particular qualifications, since each individual has a very powerful logic. The use of logic in combination with the freedom of thought by a free person are enough in order to become a philosopher. For this reason the present work is addressed as much to the general public as well as to scientists of any speciality. It aims to present fundamental principles that will help as foundation stones in the construction of answers to the questions that are placed. New questions are raised, and new ideas on confronting such questions are introduced, providing motives for younger people who wish to deal with philosophy and want to work out answers.
