A rational universe cannot be explained by anything other than the PSR. Only the PSR provides an intelligible answer to existence. Everything else involves unreason and irrationalism, hence leads to incoherence, incompleteness, inconsistency and unintelligibility. The PSR alone explains reality. Everything else is a sham and a fraud. The PSR translates into a mathematical formula: Euler’s Formula. That’s all that is needed to explain everything. It is the Source, the First Universal, the ultimate concept underlying all concepts and all percepts.
