The first two questions face anyone who cares to distinguish the real from the unreal and the true from the false. The third question faces anyone who makes any decisions at all, and even not deciding is itself a decision.
Internet Sources Later in eighteenth centuryScottish philosopher David Hume sought to develop more fully the consequences of Locke 's cautious empiricism by applying the scientific methods of observation to a study of human nature itself.
We cannot rely on the common-sense pronouncements of popular superstition, which illustrate human conduct without offering any illumination, Hume held, nor can we achieve any genuine progress by means of abstract metaphysical speculation, which imposes a spurious clarity upon profound issues.
The alternative is to reject all easy answers, employing the negative results of philosophical skepticism as a legitimate place to start.
Stated more positively, Hume's position is that Philosophy skepticism human beings do in fact live and function in the world, we should try to observe how they do so. The key principle to be applied to any investigation of our cognitive capacities is, then, an attempt to discover the causes of human belief.
This attempt is neither the popular project of noticing and cataloging human beliefs nor the metaphysical effort to provide them with an Philosophy skepticism rational justification. According to Hume, the proper goal of philosophy is simply to explain why we believe what we do.
His own attempt to achieve that goal was the focus of Book I of the Treatise of Human Nature and all of the first Enquiry. Ideas Hume 's analysis of human belief begins with a careful distinction among our mental contents: Enquiry II Thus, for example, the background color of the screen at which I am now looking is an impression, while my memory of the color of my mother's hair is merely an idea.
Since every idea must be derived from an antecedent impression, Hume supposed, it always makes sense to inquire into the origins of our ideas by asking from which impressions they are derived.
To this beginning, add the fact that each of our ideas and impressions is entirely separable from every other, on Hume's view.
The apparent connection of one idea to another is invariably the result of an association that we manufacture ourselves.
Enquiry III We use our mental operations to link ideas to each other in one of three ways: This animal looks like that animal; this book is on that table; moving this switch turns off the light, for example.
Experience provides us with both the ideas themselves and our awareness of their association. All human beliefs including those we regard as cases of knowledge result from repeated applications of these simple associations.
Hume further distinguished between two sorts of belief. Enquiry IV i Relations of ideas are beliefs grounded wholly on associations formed within the mind; they are capable of demonstration because they have no external referent. Matters of fact are beliefs that claim to report the nature of existing things; they are always contingent.
Mathematical and logical knowledge relies upon relations of ideas; it is uncontroversial but uninformative. The interesting but problematic propositions of natural science depend upon matters of fact.
Abstract metaphysics mistakenly and fruitlessly tries to achieve the certainty of the former with the content of the latter. Matters of Fact Since genuine information rests upon our belief in matters of fact, Hume was particularly concerned to explain their origin.
Such beliefs can reach beyond the content of present sense-impressions and memory, Hume held, only by appealing to presumed connections of cause and effect. But since each idea is distinct and separable from every other, there is no self-evident relation; these connections can only be derived from our experience of similar cases.Contemporary Skepticism.
Philosophical views are typically classed as skeptical when they involve advancing some degree of doubt regarding claims that are elsewhere taken for granted.
Varieties of skepticism can be distinguished in two main ways, depending upon the focus and the extent of the doubt.. As regards the former, skeptical views typically have an epistemological form, in that they. Contemporary Skepticism.

1. Philosophical Skepticism vs. Ordinary Incredulity. Even before examining the various general forms of skepticism, it is crucial that we distinguish between philosophical skepticism and ordinary incredulity because doing so will help to explain why philosophical skepticism is so intriguing.
Ancient Greek Skepticism. Although all skeptics in some way cast doubt on our ability to gain knowledge of the world, the term "skeptic" actually covers a wide range of attitudes and positions.
A survey of the history of Western philosophy. Skepticism quite properly forbids us to speculate beyond the content of our present experience and memory, yet . It is maintained that epistemological skepticism is different in theme and scope.
There are two types of skepticism: knowledge skepticism and justification skepticism (Moser et al, ).
