    "In the scholastic way of spelling out "A = A", some sort of distinction intervened between the relata, viz. the distinctio rationis ratiocinantis. To distinguish between the distinctio rationis ratiocinatae and ratiocinantis was commonplace from the sixteenth up to the eighteenth centuries. But how to make sense of a distinction that is without any foundation in the object itself? Mastri's account marks a crisis within Scotism, since his reception of Peter Aureol's conceptualism made it possible to give the d istinctio rationis ratiocinantis a metaphysical rather than a logical interpretation."

Abraham Calov (1612-1686)

"His most interesting metaphysical works are the Metaphysica divina pars generalis and the Metaphysica divina pars specialis . Calovius's logical / epistemological works, the Gnostologia and Noologia, may be of some interest, although as logic the works are weakened by the psychologism which is often found in logic texts of that period and school.

Calovius is a good example of the typical Protestant metaphysician of the 17th century. According tu Calovius, one's metaphysical studies should be guided by the truths of revealed faith, in this case orthodox Lutheranism. Without the guidance of the celestial light, all our travels into scholarly study are nothing more than pitiable wandering. But we cannot follow this celestial light unless we pay attention to both Scripture and nature. Calovius reveals himself to be a true scholastic by naming Aristotle the foremost philosopher. Thus, the main task of Calovius's work is to reconcile the revealed truths of orthodox Lutheranism with the principles of Aristotle's metaphysics. That one is so enabled to refute the errors of agnostic natural scientists, Socinians (a favourite target of Protestant attacks, this Protestant sect denied the doctrine of the Trinity and the divinity of Christ), Jesuits, Calvinists, and other heretics, so much the better. Still, both soumces of knowledge are required: without Aristotelian natural science, there will be factual errors; without Scripture, heresy. ( Hinc tot errores, tot haereses .)

Metaphysics, according to Calovius, is the wisdom of being qua being ( sapientia Entis qua Entis ). This definition should be understood as denoting one discipline, which is also called 'ontology' or 'transcendental wisdom' ( ontologia [in Greek] sive transcendentalis Sapientia ). The usual and improper sense of 'metaphysics' adopted by the Jesuit Benito Pereira (c. 1535-1610). according tu whom metaphysics is concerned with disembodied spirit, is rejected. Indeed, he says, they hallucinate who make the object of metaphysics either God or immaterial substance, and they plainly do not understand the nature of wisdom.

Thus, Calovius believes that the mistake of people like Pereira was to fail to acknowledge a notion of being which is general enough to be common both to spiritual and material beings. This, of course, may not be entirely fair to Pereira and other Thomists, since theological discomfiture may arise from claiming that God and creatures are subsumed under a general concept of being. Does this most general of concepts logically or ontologically precede God? Or is the dignity of God affected by sharing the notion of being with beings like you and me?

Metaphysics, fmally, must deal with what really is, not merely what could be. Calovius claims that truly and properly, metaphysics concerns itself with non-complex, essential, positive, real, actual being ( Ens incomplexum, per se, positivum, reale et actuale ).

Only in an attenuated sense does it contain complex, accidental, deprived beings, beings of reason, and potential beings ( Entia complexa, per accidens, privationes, Entia rationes et in potentia ). Calovius prefers to limit metaphysics tu the former, and we might not incorrectly cali him an 'actualist'. Atfer all, Calovius wonders, how does one abstract notion of being common to actual and potential being, if potential being is not truly being?"

    "This paper aims to show how the Spinozistic hermeneutical position in the Tractatus Theologico-Politicus is founded in a particular tradition, that of Johannes Clauberg, which makes a strong distinction among the sensus genuinus (i.e., the meaning intended by the author), the true meaning, and the truth. L. Meyer, a physician and friend of Spinoza, accepts this distinction but he reduces the true meaning to the truth as it is understood in the philosophy of Descartes or Spinoza. Spinoza, however, maintains the distinction between true meaning and truth, and for him the Bible keeps its holy character as long as it helps man to practice justice and charity. Human reason brings out the universal moral teachings of the Bible and it fosters a community of those who genuinely seek the truth."

    "The Logica vetus & nova published by Johannes Clauberg (1654) is directly inspired by the works of Descartes. For this reason, this text is commonly considered as the first handbook of 'cartesian' logic. Which are, therefore, the Cartesian elements distinguishing this logic from the previous ones? Our aim is to show that there are two main aspects which Clauberg derives from the works of Descartes: on the one hand the foundation of logic on the perceptio clara et distincta; on the other the role of medicina mentis assumed by logic, on the basis of a philosophical theory of prejudices that has been derived from the Principia philosophiae (but also from Bacon). Clauberg's logic, anyway, does not accept the most radical innovations of Cartesian theory of knowledge: in this way it is still bound up with the scholastic tradition."

    "It is a much neglected fact that the young Leibniz expressed particular interest for the philosophy of Johannes Clauberg, a follower of Descartes with Aristotelian outlook who taught at the University of Duisburg. Indeed he found here, against the background of Cartesianism, important impulses and preconceptions for important basic positions of his, which in many respects can be understood as extensions and unfoldings of Claubergian approaches. In this way nothing less than a story of creation and development of Leibnizian thought is uncovered, e. g. from the gnoseological (symbolism of ideas; differentiation of nominal and real definitions, truths of reason and fact; the importance of real existence for the coherence of concepts) to the ontological area (the preparation of Leibnizian monadology through the question about the character of being in the innate ideas of Descartes; development of the concept of potency by means of that of facultas to that of virtus, of the petites perceptions of Leibniz and accordingly, for the first time in intellectual history, to his basic understanding of the unconscious): Further development of the anthropological question formulation through the idea of pre-established harmony."

Alexander Gottlieb Baumgarten (1714-1762)

"Baumgarten's basic argument for the existence of a special faculty of sensitive cognition leads back to the core of his metaphysics. To be aware of the material perfection of the world from a finite point of view is, he held, possible only in a sensitive way that is not overwhelmed by abstractive concepts of the intellect. For Baumgarten, beauty is the observable phenomenon representing this material perfection, and the finite created mind is able to gain consciousness of it because of its original disposition to represent the reality and order of the world by clear but confused perceptions. Baumgarten elaborates a set of conditions for the 'art of thinking beautifully' ( ars pulchre cogitandi ). He hereby relies on the doctrines of 'special metaphysics': cosmology, psychology, and the discipline yielding the ultimate ground of the relation between these, namely natural theology.

In his account of metaphysics Baumgarten in general follows Wolff. The first main part is 'ontology' or 'general metaphysics'. This sets out the 'predicates of being'. Baumgarten interprets the principle of contradiction in a way which yields the basic ontological concept 'something' or simply 'thing' (ens): what is not 'A and not-A', i.e. 'nothing' ( nihil ), is 'something' ( non-nihil ). The universal connection of all things is governed by the principle of ratio and rationatum : whatsoever B exist, is founded in something other A, and at the same time there is something other C which is founded in B. The further universal predicates are unum, ordo, verum, and perfectum, traditionally called the 'transcendental' predicates of being.

Baumgarten's ontology manifests much sophistication. Yet there are profound difficulties which cannot be ignored. How, for example, can the universal predicates be compatible with each member of such disjunctive predicates as: necessary/contingent; changeable/unchangeable; real/unreal; singular/universal; total/partial; finite/infinite; simple/composed; substance/accidence? The universal and disjunctive predicates constitute the internal determination of the ens qua ens . They differ altogether from such external (or 'relative') predicates as: similar and diverse, simultaneous, successive, cause and caused, etc. The ontological predicates then furnish the basic material for most of the arguments of special metaphysics. In two points Baumgarten proves especially his independence from Wolff: in his doctrine of monads as immaterial, inextended substances; and in his doctrine of pre-established harmony in the absence of influxus physicus .

He herewith reinstitutes the genuine ideas of Leibniz, more than any other of the Wolffians."

If they are compared on two major issues: monadology and preestablished harmony, together with the principle of sufficient reason, concept of substance as force, concept of individual substance, it appears (as in our work on Baumgarten's metaphysics) that Baumgarten is more Leibnizian than Wolff. His metaphysics is the first Leibnizian-Wolffian philosophy; he assumes and develops, with the methodology of Wolff, the philosophy of Leibniz."

    Review of Mario Casula (1973).

Christian August Crusius (1715-1775)

"Crusius, in his Entwurf der nothwendigen Vernunftwahrheiten ( Sketch of necessary rational truths; Leipzig, 1745), divided metaphysics into ontology, theology, cosmology, and pneumatology, in explicit opposition to Wolff's ordering of the metaphysical sciences.

Ontology begins, not with first principles, but with the notion of a thing in general, directly connected with the notion of a "really given thing'. Only after introducing these notions did Crusius discuss essence, existence, and causality. Crusius regarded existence as indefinable and as a primary notion arising from sensation.

In his discussion of causality, Crusius expounded a principle of determining reason, his version of Gottfried Wilhelm Leibniz's principle of sufficient reason. Crusius held, against Wolff, that a sufficient reason suffices only for free actions insofar as they are free. Rational truths and natural events not depending on free causes need a more cogent foundation, a determining reason. This principle does not derive from the principle of identity, but rather from what we must conceive or what we cannot conceive as united or separate, and thus from a new case of the principle of cogitabilitas. Crusius, aiming at a sharper distinction between mechanism and free actions, held that the real nature of causality is unknown and that our knowledge of causal connections is based on the constant conjunction of two events in experience. This, of course, cleared the path for the members of his school to accept the Humean critique of the causal connection.

Crusius's ontology reveals a general characteristic of his metaphysics. His was not a monolithic system beginning with a single principle and deducing from it all subsequent notions and propositions, as was Wolff's. Rather, it was founded both on several independent principles and on a multitude of elementary notions that could be defined only by an appeal to reality (by their concrete representation)--notions such as existence, space, time, and force; or, in psychology, the particular powers of the soul, some mental faculties, and pleasure and pain. Through Hoffman Crusius derived this view from Locke's doctrine of simple ideas, but he supposed that the number of elementary notions (which he once called categories) could be infinite."

    "In this paper we examine some passages of a logical treatise by Christian August Crusius. It seems that Crusius anticipated what might be called the circle of deduction, first discussed by Lewis Carroll.

    The question now emerges: why was it possible for Crusius to have deeper logical insights than his contemporaries, given that he was not a brilliant logician? The answer here proposed traces these insights back to his very peculiar philosophical premisses, which have been important for Kant's development in his early career."

Johann Heinrich Lambert (1728-1777)

"A. Simple concepts. Simple, or fundamental, concepts ( Grundbegriffe) are a subclass of empirical concepts ( Erfahrungsbegriffe) and must be found by the Lockean method of collecting and inspecting ( Musterung) examples. But whereas empirical concepts may be erroneous (i.e., may have no object corresponding to them) and give only a mere delusory appearance of things, the fundamental concepts are derived from the experience of the sensu interno and must be granted even by the skeptic (the solipsist, der Egoist) who denies the existence of everything except himself and his experience.(45) The simple concepts can only be ostensively defined, not nominally. They can appear as predicates in a judgment whose subject is a complex empirical concept; but in this case the subject can be analyzed into simple concepts, and the original judgment will thereby be resolved into tautologies ("white is white"), simple negative propositions like Locke's intuited disagreements of ideas ("white is not black"), or relational propositions (such as "space has length, breadth, and height" or "motion has velocity and direction") .(46)

B. Combinations of simple concepts. Our knowledge of such propositions is a priori, for though experience is necessary if we are to have the concepts, we do not have to experience their combinations to see the truth of the propositions.(47) The various sciences are based upon some of the simple concepts (for example, geometry on that of space, chronometry on that of time, phoronomy on space and time, "agathology" on the concept of good), and Lambert builds up large and elaborate tables showing what simple concepts are involved in each of the branches of science and philosophy.(48)

But while Lambert is clear in his theory of simple concepts, his theory of their combination is no more satisfactory than that of Crusius. Lambert uses a weaker form of Crusius' criterion of what can or cannot be thought together, calling it the criterion of "thinkability" ( Gedenkbarkeit). But while thinkability is a test for a concept, something stronger is needed as a test for judgment; "not to be thought apart," or "must be thought together" as Crusius would say, are needed. This criterion of thinkability, or inseparability, applies to propositions whose predicate is included in the subject, as Leibniz thought; but obviously it will not work for that reason on propositions connecting simple subjects and predicates. Lambert sometimes appeals to the law of contradiction, which in turn is based upon the incredibility ( nicht-glauben-lassen) of contradictions(49) and sometimes to

the mere possibility of thinking a combination of ideas under maxim that "cogitabile is equal to possibile."(50) But if Gedenkbarkeit is too weak a test, the law of contradiction is too stringent, and Lambert must rightly confess that the "fons possibilitatis duos ideas combinandi has not been fully discovered."(51) It was to remain hidden until Kant clearly distinguished the synthetic a priori from the analytic; and to explain the kind of combinations Lambert and Crusius were concerned with required the whole labor of the Critique of Pure Reason.

The total system of all the simple concepts and their permissible combinations constitutes what Lambert calls the realm of truth.(52) It is equally the object of logic (i.e., the science of reason, Vernunftlehre) and ontology, which is therefore completely a priori, since it deals with objects only insofar as they are possible. Still, Lambert does not wish the realm of truth to be defined solely in formal terms as a set of non-contradictory propositions having simple concepts as their subjects. He speaks rather of a harmony(53) reigning in the realm of truth. Harmony is what later in the history of philosophy will be called "coherence." Each proposition in the system is not only consistent with all the others, but harmonizes with it in some more intimate fashion, supporting and being supported by all the others. Every erroneous proposition can be discovered by a stepwise process (Schritt für Schritt, as Lambert liked to say) of testing it against each of the others; but since every proposition is ultimately reducible to simple concepts which are always logically true, every error contains some truth which we are to discover by analysis. The most harmonious system is, by definition, the logically true system: wholly unified, with no contingencies, and completely comprehensive. Any lacuna is a warning, and any dissonance a sign of error.(54)"
