Since the ideas involved in matters of fact can be conceived as separable, for example, the idea of a hammer and the idea of glass breaking, whereas those of mathematics cannot, for example two plus two, and four, there is a fundamental difference in the knowledge we can have. But knowledge of the world is entirely founded upon matters of fact. Knowledge based on relations of ideas includes logic and mathematics.

In the course of his analysis of human apprehension, Hume, being a good empiricist, makes two claims that he believes to be self-evident: (a) all we know are our ideas of things, formed by the mind on the basis of sensory impressions and (b) all knowledge, which is perforce propositional, must be either about relations of ideas or matters of fact. There are thus three important aspects of Hume’s critique of causality: (a) the nature of causality as constant conjunction of disparate ideas (b) the skeptical conclusions about our knowledge of the world following from this and (c) the anti-metaphysical import of his argumentation. A fortiori, claims to metaphysical knowledge would be devastated. As a result, any attack on the principle of causality would inevitably have grave repercussions for knowledge about the world, or pretensions to it. By Hume’s time, causality had shifted from being primarily about things in the world, to being the way of guaranteeing the veracity of our perception of it. This task Hume undertook in his Treatise of Human Nature, Book I. As the culmination of British empiricism, Hume’s work is especially significant because he realized the importance of analyzing human apprehension both as a step in the development of a comprehensive philosophy, and in connection with the problem of causality. The figure of David Hume looms large in the philosophical tradition of English-speaking countries and his two famous analyses, of human apprehension and of causality, were the most penetrating up to his time, and continue to have great influence. In doing so, he has achieved a unique perspective on the subject which should be of great interest to those concerned with causality and any of its applications. Xavier Zubiri (1898-1983) has rethought and reformulated the question of causality in light of its historical roles, well-known criticisms, and relevant contemporary knowledge. After David Hume, however, many have questioned whether there is (or can be) any metaphysical meaning of causality, or valid inferences based upon it.

Maybe that's the intended meaning, but I'm inclined to resist interpreting Aquinas as merely asserting a tautology here.FOWLER: Zubiri's Critique of Hume's Analysis of Causality Download this text in Microsoft Word 6 format /Copiar este texto como documento MS Word 6 If I infer the meaning of the term from what he has written, I would have to conclude that a cause contains its effect virtually when it has the ability to give rise to that effect, which reduces the principle of proportionate causality to a tautology ("things only cause things they have the ability to cause"). This is all Feser writes:Īnd sometimes it is in the cause "virtually but not actually," as "when heat is caused by motion, heat is present in a sense in the motion itself as an active power" or when "the form of numbness is in the eel which makes the hand numb."įeser does not give a definition of "virtually" here. I'm having trouble understanding what it means for a cause to contain its effect virtually, though. A cause contains its effect formally when it contains its form in the same way as it exists in the effect (e.g., a man causing a man to come into being), and eminently when it contains its form in a different way from the effect and in a different kind of substance (e.g., the idea of a house existing in the mind of its builder). 22-23), the principle of proportionate causality says that every cause must contain its effect, either formally, eminently, or virtually.
