Analysis of information sources in references of the Wikipedia article "Meditations on First Philosophy" in English language version.
If Euclid is right, it is not the case that we know nothing permanently and for certain. A natural philosophy grounded in mathematics avoids the traditional objections to empirical or sensory knowledge: the sixteenth-century skeptics had been premature in despairing of any enduring systems of theoretical knowledge.
What even more precisely, therefore, is distinctive of Descartes is his 'regression' to the indubitable ego as the only possible way of combating scepticism.… Since, for Husserl, scepticism provided the goal that led the Greeks to the primal establishment of phylosophy, such a regression to the ego now emerges for the first time with Descartes as the necessary first step in philosophy. This is the 'ethernal significance' of Descartes's Meditations. They 'indicate, or attempt to indicate, the necessary style of the philosophycal beginning'.… In fact, the Cogito is the only thing in Descartes that is, according to Husserl, of any philosophical significance at all. Almost every time he refers to Descartes's Meditations in his other writings (e.g., EP I, 63; Crisis 76 [75]), it is the first two meditations that he refers to: those that solely concern the regression to the indubitability of the ego and its 'thoughts' through the offices of methodical doubt. Descartes's last four meditations do not even get a look in.
[G]reat weight must be given to the consideration that, in philosophy, the Meditations were epoch-making in a quite unique sense, and precisely because of their going back to the pure ego cogito. Descartes, in fact, inaugurates an entirely new kind of philosophy. Changing its total style, philosophy takes a radical turn: from naive objectivism to transcendental subjectivism.
