An Introduction to Environmental Philosophy 1. PHILOSOPHY Philosophy (etymologically, the love of wisdom [philo(love)+sophia(wisdom) in Greek] is the enquiry into the broadest and most fundamental questions of human knowledge and possible answers to them. Philosophy can ask a question regarding all that exists (the broadest of all questions): what is being? what does it mean to be? At the same time, philosophy can ask also the broadest and most fundamental question in a particular field of study, say, in science (this branch of philosophy is called ‘the philosophy of science’): does quantum physics tell us about the way the world really is? Now, philosophy asks not only the broadest and most fundamental questions, it is also the broadest field of knowledge. When Isaac Newton wrote the Mathematical Principles of Natural Philosophy in 1687 physics was still thought to be a branch of philosophy. In fact, at some point nearly every subject currently listed in our university’s catalog would have been considered philosophy. It is when new methods of enquiry like experiment, observation, explanation, verification, and evidential reasoning developed that philosophy was considered different from other fields of study. The most basic method of philosophy is reasoning per se without any allusion to other methodologies I have mentioned above. Hence it is a completely conceptual exercise. Being the broadest field of study, philosophy has several branches or subfields of enquiry. The study of the broadest and most fundamental questions regarding reality is called metaphysics. The most central question of metaphysics is ‘what is real?’ It is the broadest question because there is nothing beyond the real; it is the most fundamental question because on the answer to this question rests all our priorities, perspectives, and knowledge. If we believe God is the fundamental reality, of which everything else is born and to which everything else goes back, our most important priorities could become very religious and spiritual. On the other hand, if we believe the fundamental reality only the scientifically explicable material principles, our attitude to life could become scientific and factual. Similarly, the study of the broadest and most fundamental questions regarding knowledge is called epistemology. Its central question is ‘what is knowledge?’ The study of the broadest and most fundamental questions regarding human behavior is called ethics. It asks the question what the principle (value) is according to which we can call our actions good and bad. There are other sub-branches of philosophy like logic (enquiry into reasoning or inference), politics (enquiry into government and sharing of power), and aesthetics (enquiry into the nature and criteria of beauty). Since philosophy is the study of things most fundamental, all other branches of knowledge begin from a philosophical base or starting point. For example, physical sciences begin from a philosophical understanding of nature and organize their experiments and tests accordingly. They assume things that cannot be explicated through scientific methods proper. For example, modern sciences assume that there
