Leibniz Rationalism

Rationalism is the theory that opinions and actions should be based on reason and knowledge rather than religious belief or emotional, while empiricism is the theory that knowledge is derived from senses-experience which stimulated the rise of experimental science. The philosophers Descartes, Spinoza, Leibniz, Locke, Berkeley, and Hume all have different views on the existence and nature of external objects. Some see it as the view on objects as everything is sense related other see it that it is all from thought but the object is not existent.

The topic of knowledge and belief has been a subject of investigation and a primary field in philosophical research for centuries. Whether it was Aristotle or Descartes, multiple ideas on knowledge and belief arise, such as the epistemological theories of foundationalism or coherentism, which provide philosophical explanations to this debate. For the sake of this essay, and in my own opinion, knowledge should be distinguished from belief. Everyone is subject to different types of beliefs based on upbringing, however knowledge of basic items is universal, therefore it immediately becomes apparent that there is a clear distinction between the two concepts.

Throughout the history of metaphysics the question, What is? has always been answered in an incomplete,unsatisfactory or complicated manner, but Spinoza tried to answer this question in an exceptional way simply by describing God and His essence. Based on Spinoza’s views, God’s qualities can be referred to as attributes and modes are merely affections of a substance. This paper will provide a detailed view of Spinoza’s key ontological definition of God as the only substance, his attributes, and their co-relations. The study goes further to explore the major scholarly argument between Spinoza and Descartes, in regard to their view of substance, and its attributes.

The argument Renatus intends to make with this ideology is that every effect must contain the same properties as its cause, and vice versa (41). This point is the precursor to his first proof of the existence of God. The understanding is that a rock could not have been a rock unless the forces, by which it was created, also contained the qualities of a rock (41). Alternatively, as much as a substance can only exist as a result of something of equal perfection, for an idea to be derived from a cause different from its effect, the idea would have been created from nothingness. Therefore, because an idea is not (nor cannot be) nothing, it must always be the case that reality follows this cause and effect relationship (41).

The central problem of this paper that I am going to try to convince my atheist friend is that god existed. I will argue in favor of a higher being by first presenting and evaluating two argument that will be used to persuade my atheist friend. First I will explain Pascal’s argument. Second I will explain one of the arguments of Aquinas’s that is in favor of the existence of god. Then I am going to explain what’s the central difference between the two arguments is. I will conclude by stating whether I was successful in converting my atheist friend.

In Meditations on First Philosophy, Descartes takes the reader through a methodological exercise in philosophical enquiry. After stripping the intellect of all doubtful and false beliefs, he re-examines the nature and structure of being in an attempt to secure a universally valid epistemology free from skepticism. Hoping for the successful reconciliation of science and theology, Descartes works to reconstruct a new foundation of absolute and certain truth to act as a catalyst for future scientific research by “showing that a mathematical [rational-objective] physics of the world is attainable by creatures with our intellectual capacities and faculties” (Shand 1994, p.

During the 17th and 18th century two philosophers, Plato and Aristotle, arose carving for themselves a trench in the philosophical world. We can see the biggest distinction between the two in their theories of how we know things exist. The traditions of Plato and Aristotle have been dubbed rationalism and empiricism respectively. Under these traditions many well known philosophers have formed their own theories of God, existence and the material world. Through these individual theories I will show how each fits into the category of either Rationalist or Imperialist. The Plutonian philosophers to be

Rene Descartes Meditations is known to be one of his most famous works, it has also shown to be very important in Philosophical Epistemology. Within the meditation’s he provides many arguments that remove pre-existing notions, and bring it to the root of its foundation which Descartes, then will come up with his indubitable foundation of knowledge to defeat any doubt and to prove God is real. Descartes was a “foundationalist”, by introducing a new way of knowledge and with clearing up how people thought about things prior. Descartes took knowledge to its very foundations, and from there he can build up from it. In this essay, I will be discussing Descartes, and analyzing his first two meditations and arguing that he does indeed succeed in his argument.

The concept of God is central to the development of Cartesian and Spinozan philosophy. Although both philosophers employ an ontological argument for the existence and necessity of God the specific nature of God differs greatly with each account. While Descartes suggests a Judeo-Christian concept of God, Spinoza argues a more monistic deity similar to that of the Hindu tradition. The most significant difference however, lies within the basis and structure of each argument itself. Considered from an analytical standpoint through the lens of Gotlobb Frege, Descartes' proof of God possesses both sense and reference and is therefore capable of expressing the

The concept of mind and body interactions has been debated among many modern philosophers. Some believe that our minds and bodies are different things, thus existing separately, while others believe that they exist as a whole. In this paper, I will be introducing two rationalist philosophical views regarding this topic, one which is by Rene Descartes and the other by Gottfried Wilhelm Leibniz. Rationalists, in philosophical terms, are the ones who obtain their knowledge through reasoning rather than the human senses. Descartes and Leibniz both have similar perspectives, but Leibniz takes a slightly different approach to improve Descartes’ argument. This paper will first show Descartes’ original argument, an example that proves the argument to be invalid, and then lastly, a revised version of the argument with Leibniz’s help.

In his work Meditations on First Philosophy, published in 1641, René Descartes sets out to establish a set of indubitable truths for the sciences. He begins by discarding all of his beliefs, then works to rebuild his beliefs based on careful thought. Descartes clearly states this goal, saying in the First Meditation, “I will work my way up… I will accomplish this by putting aside everything that admits of the least doubt” (I, 17). He is able to establish his own existence, but struggles to move beyond his internal thoughts to discuss external objects. Descartes decides that the Christian God is the bridge he needs to escape the confines of his own mind, and argues for the existence of God in the Third Meditation in order to move on to discussing the physical world. In this paper I will argue that Descartes’ rationalistic project would have been improved without an appeal to the Christian God, although I will also argue that Descartes thinks this appeal is necessary.

Rene Descartes was a rationalist who believed that knowledge of the world can be gained by the exercise of pure reason, while empiricist like Locke believed that knowledge of the world came through senses. Descartes from his meditations deduced from intuitive first principles the existence of self, of God, of the mind as a thinking substance and the extended body as a material substance whereas Locke, asserts that knowledge is acquired through perception, direct sensory of the world, reflections, the mental processes of breaking down complex impressions into simple ones and comparing them, conceptualizing them and recommending them to form new philosophies.

Faith and reason were two modes of belief that dominated the history of Western Civilization. Both faith and reason were popularized as tools to understand the universe in Greco-Roman and Judeo-Christian eras. By conflicting with each other, these two modes of belief sparked a lot of controversy. Reason or rationality is belief based on concrete evidence and logic. The development of one’s reason relies heavily on observation and questioning. Greco-Roman philosophers believed in the power of the human mind to understand the world. So in order to find ultimate truth, Greco-Roman philosophers dedicated their lives to perfecting their reasoning skills and encouraged those around them to do the same. Contradictory to reason, faith is the

Upon talking about the history of modern philosophy, one of the most important philosophers, who is considered as the father of the philosophy in this period, is Descartes. He was a pioneer for the movement of the new trend of philosophy and became a break between the medieval philosophy and the modern philosophy. Being educated in the environment of medieval philosophy, specifically in the school of Jesuits, Descartes received the system of scholastic philosophy as his foundation for making a new start into the history of philosophy. In his life, Descartes tried to establish a system of philosophy which was suitable to the development of society and science. To do that, he did not collapse pre-philosophical systems, but somehow he ignored their values. In his Meditations he says “Once in my life I had to raze everything to the ground and begin again from the original foundations, if I wanted to establish anything firm and lasting in the sciences.” Therefore, he just could begin a new system of philosophy which, he thought, would be a certain and firm foundation to get knowledge. However, to build up the principles for this foundation, Descartes had to use the concept of God in his arguments. The existence of God became an important means for the construction of his new philosophical system. Hence, I will emphasize on the importance of God in this paper by discovering the role of God as a means in Descartes’ main points of reasoning, particularly God with the method of

Rene Descartes was a philosopher of the 17th century. He had this keen interest in the search for certainty. For he was unimpressed with the way philosophy is during their time. He mused that nothing certain was coming forth from all the philosophical ideologies. He had considered that the case which philosophy was in was due to the fact that it was not grounded to something certain. He was primarily concerned with intellectual certainty, meaning that something that is certain through the intellect. Thus he was named a rationalist due to this the line of thought that he pursued. But in his work in the meditation, his method of finding this certainty was skeptical in nature; this is ‘the methodic doubt’.
