By science here I mean the habit of demonstrating propositions, i. When properly employed, then, human reason can discern groups of facts, establish a certain order and interconnectedness between these facts, and ultimately justify them as being certain parts of human knowledge. Put slightly differently, science is a disposition or ability of the human mind to conceive the facts of reality in an ordered and structured way. Individual sciences, therefore, such as theology, cosmology, or psychology, are simply the various sets, or subsets of demonstrable cognitions and the principles including axioms, definitions, and empirical facts from which they are derived.
The central idea here is that certain truths are known prior to, and serve as a basis for discovering, other truths. And just as there are certain facts that are more fundamental and serve as a basis for discovering other facts, there are, Wolff believes, certain sciences whose subject matter is more basic and which ultimately stand as the foundation for other sciences that have a more specialized focus. A reasonable objection to Wolff might be that his conception of the rational order of science is based on an unwarranted assumption about the harmonious order he believes to be present in all facets of reality.
By virtue of the very interconnectedness of the different disciplines most notably, mathematics with physics and physics with astronomy the claim for an intrinsic rational order among the sciences is seen by Wolff to be a pragmatic explanation for what is already largely observed and accepted as the status quo among many natural philosophers GL: c. Unlike Leibniz, Wolff was much more willing to embrace the advances brought in the name of Newtonian natural philosophy on this, see the next section.
Now because of its subject matter, philosophy is considered by Wolff to be the broadest and most fundamental science. In the classification of sciences given in his Preliminary Discourse , Wolff first divides philosophy into two branches: practical philosophy, on one hand, and theoretical philosophy, on the other. Practical philosophy deals in general with human actions and includes morality, politics, jurisprudence, and economics. As a brief aside, Wolff and the Critical Kant hold very different views on the relationship between practical and theoretical philosophy.
Whereas Wolff believes that all of practical philosophy is subordinated to metaphysics i. Wolff, in stark contrast, maintains that discoveries and conclusions made in practical philosophy are necessarily based upon prior conclusions drawn from ontology or metaphysics. Philosophical rationalism can be understood to involve any or all of the following: commitment to the existence of innate ideas or principles, the privileging of a priori cognition to cognition known a posteriori , and endorsement of the principle of sufficient reason PSR. Such a caricature, however persistent, is to be firmly rejected on both historical and philosophical grounds.
Historically, this misrepresentation of Wolff as an arch-rationalist ignores his liberal borrowings from, and deep engagement with, empiricistic and scientifically-minded thinkers, most notably Locke and Newton. It can now be seen how common cognition is distinguished from the cognition of a philosopher, namely, one who has no understanding of philosophy can learn many things about what is possible from experience, yet, he will not know how to indicate the reason why it [i.
For instance, he learns from experience that it can rain, but cannot say how it happens […] nor indicate the causes why it rains.

This would suggest, then, that for Wolff the path to genuinely philosophical truth is ultimately that of reason pursued independently of experience. Kreimendahl Unsurprisingly, Wolff sets up his distinctive emphasis on experience and introduces his innovations in philosophical method in conscious opposition to his rationalist predecessors. Instead, Wolff recommends near the end of the German Logic that the philosopher should be trained. Cataldi Madonna Philosophy is a science of possible and actual reality.
Kant and his German Contemporaries
Although there is an important sense for Wolff in which ontology is relevant for, and even necessarily grounds cosmology and the other special sciences, cosmology itself stands in a grounding relationship to physics that is, yet again, a more narrow and specialized discipline Cosm. Just as there are certain principles and certain truths established in ontology that are relevant for cosmology, there are certain principles and certain truths established in cosmology that are relevant for the more specialized science of physics.
It is regarded by him to be a self-evident first principle, its truth made manifest through our inability to think in a manner contrary to it. In the Ontologia , he writes:. We experience…[ PC ]… in the nature of our mind, in that, while it judges something to be, it is impossible at the same time to judge the same not to be…. We recognize the fact of our own existence by recognizing the psychological impossibility of denying it.
But if it were possible both to affirm and also deny our own existence simultaneously , then the experience of certitude that accompanies this cognition would thereby be undermined. Wolff contends that PC is not only for our thinking but, in defining the limits of what is conceivable or not, also serves to distinguish the possible from the impossible.

So, impossibility, defined formally, is that which involves a contradiction, whereas that which does not is taken to be possible. What is possible as a concept is simply reducible to what is possible as a thing. The realm of concepts and the ontological realm of objects converge in the Wolffian system Kuehn A possible concept, consequently, is that which corresponds to a possible object Ont. Nothing, by definition, is not thinkable or conceivable.
Although existing things are included in his overall description of reality, they are not as a class of objects his primary focus. The idea that everything has a sufficient reason is presented formally by Wolff as the principle of sufficient reason. In this discussion, Wolff appears to give two separate accounts of the theoretical origin of the principle.
Although prima facie , it is unclear why Wolff attempts to advance both views, it is perhaps worth pointing out the difference between 1 being able to be demonstrate the truth of a proposition and 2 knowing the truth of a proposition because it is self-evident.
While demonstrating the truth of a proposition yields knowledge of it, to know a proposition because it is self-evident may or may not mean the proposition is also demonstrable. There is no inconsistency, for example, in holding that one and same proposition is both self-evident and demonstrable. A proposition could be known immediately one way and yet, in another way, follow as a conclusion of a sound deductive argument. The first is that PSR is never contradicted by experience; the second is that we can recognize singular instances, or examples, of it in our experience of the world, and the third is that we have an inquisitive attitude toward our surroundings and future life Ont.
For Wolff, these characteristics are not regarded as empirical evidence for PSR , but rather that PSR is a necessary presupposition for these characteristics to be a part of our conscious experience. Thus by simply reflecting on the nature of our understanding of the world, Wolff believes that we arrive at the manifest truth of PSR. Now according to Wolff there are at least four self-evident axiomatic principles of human thought: PC , the principle of excluded middle, the principle of certitude or principle of identity , and PSR Ont.
Of these, only PC is indemonstrable in the sense that the truth of the principle cannot be proved to follow from a formal deductive inference.

As we have seen, Wolff believes that we gain assurance of the truth of this principle by attending to the psychological experience of not being able to both affirm and deny our own existence in introspection. The remaining principles, however, are demonstrable in the strict sense and each, he believes, can be derived from PC. Nothing exists without a sufficient reason for why it exists rather than does not exist. That is, if something is posited to exist, something must also be posited that explains why the first thing exists rather than does not exist.
Let us assume that some A exists without a sufficient reason for why it exists rather than does not exist. The crucial premise italicized above purports to reveal a contradiction that follows from the assumption that something exists without a sufficient reason. According to Wolff, every being is endowed with an essential nature. Possible things have natures insofar as they as are comprised of a number of non-contradictory determinations or predicates.
Different sets of determinations, and the relationships among these determinations, serve as the principle of individualization within the realm of possible things. Hence, to provide the reason for a possible thing is simply to enumerate the determinations that make that thing the kind of possible thing that it is. If, on the other hand, the something to which a reason is provided is an actual i.
Recall that for Wolff existence is simply a predicate or determination of possible things. GL: c. That is to say, although there is a certain set of specifiable determinations that is sufficient to pick out a given possible thing among all possible things, the total set of its determinations is not specifiable. A being, in the most general sense, is comprised of three different types of determinations: essentialia , attributes, and modes.
Hinske, Norbert 1931-
Whereas essentialia and attributes are both necessary properties of a thing, modes are contingent or accidental properties. Thus to say a nominal being is indeterminate is to say that there are modes of it that may or may not be present. In the weakest sense, since existence is a mode, and nominal beings do not exist as such but are able to come into existence under certain conditions, all nominal beings are indeterminate.
Yet as a Principle of Becoming, PSR serves to furnish the causes, or grounds, for why a real individual comes into actuality. Recall that for Wolff a being in the most general sense is any possible thing. Possible things have essential natures insofar as they are composed of a number of non-contradictory determinations or predicates. The essence of any given possible thing is its principle of being, or principle of individualization.
Whereas the essence of a simple being is defined by its essential properties, the essence of a composite being is defined by the manner in which its parts are combined together. A being is called composed which is made up of many parts distinct from each other. The parts of which a composite being is composed constitute a composite through the link which makes the many parts taken together a unit of a definite kind. In one respect, simple beings and composite beings are not simply two different species of beings. It is not the case, for example, that within the realm of all possible things simple beings exist separate from, and in addition to, composite beings.
Strictly speaking, the only substantial things to exist at any level of reality are simple substances. Furthermore, essential properties should not be viewed as the accidents of substance because, according to Wolff, they are the substance itself. And according to Wolff, there are three basic classes of accidents: proper attributes, common attributes, and modes Ont.
Proper attributes are the properties of a thing that are determined by all the essentialia taken together, and common attributes are the properties of a thing that are determined by only some, but not all, its essentialia. Modes, in contrast, are only contingent accidents of substance. They are the properties of a thing that may or may not be present, and if actually present, they are causally the result of some contingent state of affairs. Cosmology, as a special metaphysical science, is the study of the world-whole in general. The world, as such, is an extended composite of extended composites.
The world is a collection of mutable things that are next to each other, follow upon one another, but which are overall connected with one another. In precise terms, Wolff believes the world is an extended whole that is composed of a finite number of interacting physical bodies.
captive8.smarthotspots.com/81-conocer-chicas.php To better understand the types of cosmological claims that Wolff defends about the universe, it is perhaps helpful to consider first his conception of physical bodies. Ultimately, the conclusions that Wolff draws at the macroscopic level about the world-whole are simply extrapolated from his analysis of physical bodies. To facilitate our discussion, we should identify the three levels of description that Wolff employs when giving his two perspective account.
Identifying these three different levels is helpful in understanding at what respective point the mechanical and metaphysical accounts each terminate or bottom out. Each atomic element is defined, or individuated, by its own distinctive internal state and each is considered to be indivisible in-itself. The second level of description that Wolff employs when giving his account of bodies is the microphysical level. The occupants of this level are the primitive parts of bodies which Wolff calls corpuscles or material atoms. That is called an atom of nature which is indivisible in itself because it is devoid of parts into which it can be divided.
That is called a material atom which in itself is able to be divided, but for actually dividing it, existing causes in rerum natura are not adequate. Material atoms or corpuscles are indivisible in the sense that there is nothing within the world that is capable of reducing them into further parts. Corpuscles represent the lowest level of explanation that is possible within a mechanical account of bodies.
