Doubting Descartes’ Doubt
Meditations of Descartes presents a series of arguments about a thinking thing and a God’s existence. In this essay, I will doubt his reasoning by pointing out at some fallacies. In search of a foundation of knowledge, Descartes starts from the scratch by undermining everything that he knows. He asks himself what could ground his […]
Galileo on Secondary Qualities of the Matter
Is heat a quality of the matter which we feel when it is heated or it is in a sensation of a body? In The Assayer, Galileo starts with the proposition “Motion is the cause of heat”. So, he wants to undermine a commonly held conception that heat is a quality which resides in the […]
Bacon’s Idols of the Mind
Sir Francis Bacon (1561–1626) was a successful English lawyer, politician, scientist, orator and philosopher. His works were enormously influential during a scientific revolution, in which Bacon proposed a great reformation of all process of knowledge.

On What God Did Wrong
Leibniz, unlike other rationalists before him, exemplified a more comprehensive universe that was chosen by God as the best of all possible worlds. This perfect world is characterized by an infinite number of simple substances “monads” which are non-spatial and non-temporal entities. In this paper, I shall try to break into the Leibniz’s system to […]
Locke on Time
In the Essay Concerning Human Understanding, Locke explains how we come out with ideas of duration, eternity and time. We receive ideas of duration and measures of it from reflection and sensation, two foundations of knowledge. First, we observe how our ideas are formed in our minds: some begin to appear, others vanish. So, […]
Locke on Active and Passive Power
According to Locke, power is two-fold. Active power is able to make any change, while passive power is able to be changed. For example, fire has a power to meld gold, while gold has a power to be melted. Similarly, the sun has a power to blanch wax, while wax is able to be blanched […]
Locke on Liberty
For Locke, the idea of liberty arises from the power of the mind over the actions of the man. Freedom consists in our being able to act or not act, according as we shall choose or will. Locke gives an example of a man who is carried and locked into a room while asleep. When […]
Locke on Personal Identity
In the chapter XXVII of the Essay Concerning Human Understanding, Locke reflects on what identity consists in. He starts with identity of substances which can be divided into three sorts: God, finite intelligences and bodies. God’s identity cannot be questionable as he is eternal, unalterable and everywhere. Identity of finite intelligences is defined by relation […]
Locke on Simple and Complex Ideas
For Locke, men do not have native ideas. Our minds are furnished with ideas either through perception of external sensible objects or through the internal operations of our minds, perceived and reflected on by ourselves. So, sensation and reflection are two fountains of knowledge from which come all the ideas such as whiteness, sweetness, thinking, […]
Locke on Essence
Locke distinguishes the real essence from the nominal one. The real essence is some unknown insensible constitution of things on which their sensible qualities depend. In other words, it is a foundation from which all properties of things flow. For instance, the real essence of a gold ring is a constitution of its parts, on […]
