'Michael Ayer's magisterial Locke is the philosophical work of the year and, no doubt, of the decade. It costs the price of a weekend to Brighton but is much more rewarding.' - Terry Eagleton, The Independent on Sunday
'This book is something of a tour de force ... the bare simplicity of its title belies its complexity and richness.' - Journal of Philosophy

'A distinguished addition to Lockean studies, which will doubtless be widely used and discussed in coming years.' - Mind
'Anybody who dares to claim there is nothing to be learnt from philosophy's history will have to contend with these volumes.' - Times Higher Education Supplement
