This is without doubt the ne plus ultra of John O'Loughlin's philosophical quest to nail things as comprehensively and logically as possible, and in that respect it even surpasses his loose trilogy of 'Thoughts', from Notable Thoughts and Quotable Thoughts to Final Thoughts that preceded it, thereby concluding his thinking about class and gender on the most comprehensively exacting of logical and structural terms, compared to which he has no peers, least of all in the English-speaking world into which he fits rather uncomfortably as an intellectual and spiritual outsider who has never compromised his way of thinking or sought the approval of the intellectual establishment in Britain, or the so-called British intelligentsia, for whom, in any case, he has nothing but contempt.
