Ivette Fuentes explains: “Science and philosophy share common goals. They aim at developing and deepening our understanding of reality, at uncovering the basic constituents of the Universe and its fundamental laws. Science and philosophy also share a common past. … But the overlap between science and philosophy is not only a matter of the past. In our present search for knowledge there are many moments in which the lines between them blur. Every single scientific theory and philosophical exploration starts with questions and with reflection upon them. Basic ideas are produced in order to provide answers to these questions. These ideas are developed though critical and logical thinking. At this point science and philosophy are indistinguishable. …  Once a new scientific theory is proposed, it is not only confronted with experiments (when possible) but also to philosophical scrutiny. Once a theory is born, there is an unavoidable need to interpret the objects of the theory and its results. At this stage science and philosophy again come close together.”
