Husserlian phenomenology has been interpreted as a method of knowledge that can be applied to different domains and which would compete with other methods to give us a better understanding of the “real”, the “man” or “society”. Moreover, “phenomenological idealism” has been presented as an “ontological” or “metaphysical” thesis, in the pre-critical sense of the term. The goal of this study is to suggest that these two theses imply the tacit identification of the natural attitude and the phenomenological one, avoiding the difference between the objects to which these attitudes relate. Therefore, a phenomenological truth does not anticipate any opinion about the “world”.

Shadows are intriguing phenomena. They do not have mass or energy. So, they are unable to have some basic characteristics of the objects of which they are shadows: they cannot move by themselves and they cannot experience the same kind of changes. At first sight, any theory of perception can skip this optical phenomenon or look at it only as a side-effect. Actually, in order to be seen objects must be illuminated and one of the consequences of this is that they project a shadow over the surrounding space. Is that all? In this paper I will argue that, from a phenomenological point of view (or at least from a Husserlian oriented phenomenology), shadows, with their specific hyletic data, must be considered as an element of the process of constitution of spatial-temporal objectivities. In other words, shadows no less than other predicates, like extension or hardness, although in a different manner, belong to the a priori structure of those objectivities. This means that their ontological status is quite different from that of fictitious objects or hallucinations. To show this I will draw mainly in Husserl’s Lesson Thing and Space, from 1907, and other unpublished texts during Husserl’s lifetime, like the second volume of the Ideas and the Lesson of 1925 on Psychological Phenomenology.

Our goal is to investigate the extent of the appropriation, by hermeneutic phenomenology, of the concept of transcendental at work in descriptive psychology, where it plays the role of a universal principle of the constitutive genesis of intentionality. We aim to clarify how the very mode of operation of Husserlian phenomenology is crucial to the elaboration of fundamental ontology. Our hypothesis is that intentionality leads Heidegger to the discovery of time as a transcendental principle, of being as an a priori, and of comprehensibility that enables the signification of entities in general as a previous structure of the a priori.

This paper claims that there is an epistemological evidence of an unavoidable gap between purely formal sciences (sciences of essences) and the empirical sciences for which they provide the foundation. A second key theme is the way that all empirical sciences are grounded in a pure science of essences. At the same time, I endeavour to explain how the insights Weyl gleaned from Husserl played an important role in his scientific work, and to show how Einstein’s major work exhibit important parallels to Weyl’s work, thereby establishing phenomenology both as an indirect historical influence and a systematic underpinning for Einstein’s work in theoretical physics. In so doing, this paper seeks to show how some of the most basic problems that Einstein addresses have a kinship not just to problems addressed in a completely different context by Husserl and his circle, but also to perennial problems in ontology and epistemology that go back to Kant, Hume and Leibniz. The conclusion highlights how phenomenology influenced Einstein, but also how Einstein’s work on relativity had an important influence on the work of the most important phenomenologist of the twentieth century, namely Husserl in his Crisis of European Sciences.

This article is primarily concerned with the articulation of a defensible position on the relevance of phenomenological analysis with the current epistemological edifice as this latter has evolved since the rupture with the classical scientific paradigm pointing to the Newtonian-Leibnizian tradition which took place around the beginning of 20^th century. My approach is generally based on the reduction of the objects-contents of natural sciences, abstracted in the form of ideal objectivities in the corresponding logical-mathematical theories, to the content of meaning-acts ultimately referring to a specific being-within-the-world experience. This is a position that finds itself in line with Husserl’s gradual departure from the psychologistic interpretations of his earlier works on the philosophy of logic and mathematics and culminates in a properly meant phenomenological foundation of natural sciences in his last major published work, namely the Crisis of European Sciences and the Transcendental Phenomenology (Husserl, 1962). Further this article tries to set up a context of discourse in which to found both physical and formal objects in parallel terms as essentially temporal-noematic objects to the extent that they may be considered as invariants of the constitutional modes of a temporal consciousness.
