What is the tone of the passage?

Directions: Answer the given question based on the following passage:

If physics leads us today to a worldview that is essentially mystical, it returns, in a way, to its beginning 2,500 years ago. It is interesting to follow the evolution of Western science along its spiral path, starting from the mystical philosophies of the early Greeks, rising and unfolding in an impressive development of intellectual thought that increasingly turned away from its mystical origins to develop a world view which is in sharp contrast to that of the Far East. In its most recent stages, Western science is finally overcoming this view and coming back to those of the early Greek and the Eastern philosophies. This time, however; it is not only based on intuition, but also on experiments of great precision and sophistication, and on a rigorous and consistent mathematical formalism.

The roots of physics, as of all Western science, are to be found in the first period of Greek philosophy in the sixth century B.C., in a culture where science, philosophy and religion were not separated. The sages of the Milesian school in Ionia were not concerned with such distinctions. Their aim was to discover the essential nature, or real constitution, of things that they called ‘physics’. The term ‘physics’ is derived from this Greek word and meant therefore, originally, the endeavor of seeing the essential nature of all things.

This, of course, is also the central aim of all mystics and the philosophy of the Milesian school and indeed havea strong mystical flavor. The Milesians were called ‘hylozoists’, or ‘those who think matter is alive’, by the later Greeks, because they saw no distinction between animate and inanimate, spirit and matter. In fact, they did not even have a word for matter, since they saw all forms of existence as manifestations of the ‘physics’, endowed with life and spirituality. Thus, Thales declared all things to be full of goods and Anaximander saw the universe as a kind of organism which was supported by ‘pneuma’, the cosmic breath, in the same way as the human body is supported by air.

The monistic and organic view of the Milesians was very close to that of ancient Indian and Chinese philosophy, and the parallels to Eastern thought are even stronger in the philosophy of Heraclitus of Ephesus.
