For there is no universal schema which could be applied mechanically to the interpretation of the writings of thinkers, or even to a single work of a single thinker. A dialogue of Plato – the Phaedrus, for example, the conversation on beauty – can be interpreted in totally different spheres and respects, according to totally different implications and problematics. This multiplicity of possible interpretations does not discredit the strictness of the thought content. For all true thought remains open to more than one interpretation – and this by reason of its nature. Nor is the multiplicity of possible interpretations merely the residue of a still unachieved formal-logical univocity which we properly ought to strive for but did not attain. Rather, multiplicity of meanings is the element in which all thought must move in order to be strict thought.
