=== Natural philosophy in the early modern period ===
The scientific method has ancient precedents, and Galileo exemplifies a mathematical understanding of nature, which is a hallmark of modern natural scientists. Galileo proposed that objects falling regardless of their mass would fall at the same rate, as long as the medium they fall in is identical. The 19th-century distinction of a scientific enterprise apart from traditional natural philosophy has its roots in prior centuries. Proposals for a more "inquisitive" and practical approach to the study of nature are notable in Francis Bacon, whose ardent convictions did much to popularize his insightful Baconian method. The Baconian method is employed throughout Thomas Browne's encyclopaedia Pseudodoxia Epidemica (1646–1672), which debunks a wide range of common fallacies through empirical investigation of nature. The late-17th-century natural philosopher Robert Boyle wrote a seminal work on the distinction between physics and metaphysics called, A Free Enquiry into the Vulgarly Received Notion of Nature, as well as The Skeptical Chymist, after which the modern science of chemistry is named, (as distinct from proto-scientific studies of alchemy). These works of natural philosophy are representative of a departure from the medieval scholasticism taught in European universities, and anticipate in many ways, the developments that would lead to science as practiced in the modern sense. As Bacon would say, "vexing nature" to reveal "her" secrets (scientific experimentation), rather than a mere reliance on largely historical, even anecdotal, observations of empirical phenomena, would come to be regarded as a defining characteristic of modern science, if not the very key to its success. Boyle's biographers, in their emphasis that he laid the foundations of modern chemistry, neglect how steadily he clung to the scholastic sciences in theory, practice and doctrine. However, he meticulously recorded observational detail on practical research, and subsequently advocated not only this practice, but its publication, both for successful and unsuccessful experiments, so as to validate individual claims by replication.

For sometimes we use the word nature for that Author of nature whom the schoolmen, harshly enough, call natura naturans, as when it is said that nature hath made man partly corporeal and partly immaterial. Sometimes we mean by the nature of a thing the essence, or that which the schoolmen scruple not to call the quiddity of a thing, namely, the attribute or attributes on whose score it is what it is, whether the thing be corporeal or not, as when we attempt to define the nature of an angel, or of a triangle, or of a fluid body, as such. Sometimes we take nature for an internal principle of motion, as when we say that a stone let fall in the air is by nature carried towards the centre of the earth, and, on the contrary, that fire or flame does naturally move upwards toward heaven. Sometimes we understand by nature the established course of things, as when we say that nature makes the night succeed the day, nature hath made respiration necessary to the life of men. Sometimes we take nature for an aggregate of powers belonging to a body, especially a living one, as when physicians say that nature is strong or weak or spent, or that in such or such diseases nature left to herself will do the cure. Sometimes we take nature for the universe, or system of the corporeal works of God, as when it is said of a phoenix, or a chimera, that there is no such thing in nature, i.e. in the world. And sometimes too, and that most commonly, we would express by nature a semi-deity or other strange kind of being, such as this discourse examines the notion of.
Natural philosophers of the late 17th or early 18th century were sometimes insultingly described as 'projectors'. A projector was an entrepreneur who invited people to invest in his invention but – as the caricature went – could not be trusted, usually because his device was impractical. Jonathan Swift satirized natural philosophers of the Royal Society as 'the academy of projectors' in his novel Gulliver's Travels. Historians of science have argued that natural philosophers and the so-called projectors sometimes overlapped in their methods and aims.

== Current work in the philosophy of science and nature ==
In the middle of the 20th century, Ernst Mayr's discussions on the teleology of nature (see Teleology in biology#Irreducible teleology) brought up issues that were dealt with previously by Aristotle (regarding final cause) and Kant (regarding reflective judgment).
Especially since the mid-20th-century European crisis, some thinkers argued the importance of looking at nature from a broad philosophical perspective, rather than what they considered a narrowly positivist approach relying implicitly on a hidden, unexamined philosophy. One line of thought grows from the Aristotelian tradition, especially as developed by Thomas Aquinas. Another line springs from Edmund Husserl, especially as expressed in The Crisis of European Sciences. Students of his such as Jacob Klein and Hans Jonas more fully developed his themes. Last, but not least, there is the process philosophy inspired by Alfred North Whitehead's works.
Among living scholars, Brian David Ellis, Nancy Cartwright, David Oderberg, and John Dupré are some of the more prominent thinkers who can arguably be classed as generally adopting a more open approach to the natural world. Ellis (2002) observes the rise of a "New Essentialism". David Oderberg (2007) takes issue with other philosophers, including Ellis to a degree, who claim to be essentialists. He revives and defends the Thomistic-Aristotelian tradition from modern attempts to flatten nature to the limp subject of the experimental method. In Praise of Natural Philosophy: A Revolution for Thought and Life (2017), Nicholas Maxwell argues that we need to reform philosophy and put science and philosophy back together again to create a modern version of natural philosophy.
