People have always been discussing different matters connected with the question of life. Questions of origin of our life, its sources and value have always been actual and keen, and philosophers of all epochs have been discussing them As a result of their discussion the idea of a great value of human life appeared and became the most important and even generic in terms of philosophy. However, with the development of society and civilization, new sense of this question was introduced. It became obvious that not everything is so clear with an understanding of the value of human life. The question obtained its new actuality with mass introduction and development of the practice of abortions. The main point to discuss is whether it is possible to consider this organism as a human being or not. A great number of adherers of different directions appear. Someone believes that fetus is the same human being as a common man and has its own right to live and exist. Another group believes that it is just a set of dividing cells, which does not have any conscience and soul. From this point of view lungs or stomach have the same right to be called a human being as a developing fetus has. Moreover, there are a lot of other questions to discuss connected with this issue. First of all, everyone has its own opinion whether a mother has right to manage this fetus and do everything she wants or she is just an incubator which has no rights to interrupt fetuss development, and she just has to do everything to guarantee the best conditions for its growth. Another important question raises. There is a great number of different opinions on whether abortion should be legalized or not. Taking into account all previous debates on this question, it is possible to suggest how important this issue is. Legalization of abortions depends on debates on two previous questions, and sometimes it is very difficult to make a decision. That is why there is a great number of different countries in the world with a different approach to this question. Somewhere it is legalized. However, there is a great number of countries where abortion is strongly prohibited. Moreover, this question also touches some religious matters, and it makes this issue even more disputable. Church and religion play a great role in our life, and that is why their influence in the decision of this question is very strong. With this in mind, it is possible to say that the question of abortion is a very keen issue which sets the table for a great number of different debates. However, for me, it is clear that abortions should be legalized, as I totally agree with Judith Thomsons statement that a newly fertilized ovum is no more person than an acorn is an oak tree (Thomson 1971). In this work, I argue that prohibition of abortions is wrong for reasons that it is impossible to consider this set of sells to be a human being and that sometimes they are needed just to save the life of a mother. However, there is another point of view introduced by Don Marquis in his article Why Abortion Is Immoral. In this article, the author is stressing the moral aspect of this question. He says that human being is not just a set of some biological factors, and it is not biology which determines a human being. He underlines the simplicity of a choice if to consider human beings to be a biological category (Marquis, 1989). He stres
