My awareness of constructing an objective truth would never provide me with anything more than an objective truth for me, and my greatest attempt at impartiality would never enable me to prevail over my subjectivity (as Descartes so well expresses it by the hypothesis of the malignant demon), if I had not, underlying my judgements, the primordial certainty of being in contact with being itself, if, before any voluntary adoption of a position I were not already situated in an intersubjective world, and if science too were not upheld by this basic δοξα.
