Key Arguments

• Husserl claims ‘in apriori transcendental phenomenology, all apriori sciences without exception originate with an ultimate grounding, thanks to its correlational research’.
• He adds that these sciences, ‘taken with this origin, … belong within an all-embracing apriori phenomenology itself, as its systematically differentiated branches.’
• He defines this system as ‘the systematic unfolding of the all-embracing Apriori innate in the essence of a transcendental subjectivity (and consequently in that of a transcendental intersubjectivity) — or as the systematic unfolding of the universal logos of all conceivable being.’

It is plain that the actual carrying out of the indicated investigations would have to lead to all the concepts which, as unexplored, function as fundamental concepts in all positive sciences, but which accrue in phenomenology with an all-round clarity and / distinctness that leave no further room for any conceivable questionableness. We can now say likewise that, in apriori transcendental phenomenology, all apriori sciences without exception originate with an ultimate grounding, thanks to its correlational research, and that, taken with this origin, they belong within an all-embracing apriori phenomenology itself, as its systematically differentiated branches. This system of the all-embracing Apriori is therefore to be designated also as the systematic unfolding of the all-embracing Apriori innate in the essence of a transcendental subjectivity (and consequently in that of a transcendental intersubjectivity) — or as the systematic unfolding of the universal logos of all conceivable being.

In other words: As developed systematically and fully, transcendental phenomenology would be ipso facto the true and genuine universal ontology — not, however, just an emptily formal universal ontology, but also one that comprised in itself all regional existential possibilities, and did so in respect of all the correlations pertaining to them.
