*Functionenlehre,*written before 1834, to be part of*Grössenlehre.*It contains the famous Bolzano function which is continuous on an interval [*a*,*b*] but not monotonic on any subinterval. Given two points in the interval at which no derivative exists, Bolzano showed there was an point lying between them at which no derivative exists. - Bernard Bolzano,

*Spisy Bernarda Bolzano - Bernard Bolzano's Schriften*Vol.**3,**Von dem besten Staate (About the ideal state), Edited and Einführende Betrachtungen by A Kowalewski (Královská Ceská Spolecnost Nauk, Prague, 1932).Third publication of the Bolzano Committee. Bolzano, in this work, argues for an ideal human society based on the absolute equality of all people in the society. He argues that owning large amounts of property does not merit respect but should be viewed as possibly having been acquired through immoral and/or illegal means. Even if legally acquired, he believes, such wealth is merely the "quest of riches blessed by law". He regrets that many people have to work so hard to earn enough to feed their families that they damage their health.

*Their chief merit lies in the clear presentation of definitions, theorems, proofs, and remarks. Evidently Bolzano had no inkling of the work of his great contemporaries: Gauss, Bolyai and Lobachevsky. For him parallelism presented no problem; he regarded direction as a primitive concept.* - Bernard Bolzano,

*In the national library in Vienna there are nine folios ... written by Bolzano himself; the first of these has the title 'Anti-Euclid'. The text is published here for the first time. E Winter conjectured*(*in*1933)*- without proof - that these folios constitute meagre fragments of Bolzano's work 'Anti-Euclid' which - according to Bolzano's own report - was lost*(*it is perhaps possible that the lost 'Anti-Euclid' was written "according to such a detailed plan"*)*, and that this work contained the concept of non-Euclidean geometry.

*This volume in the series of posthumous writings of the Collected works of Bernard Bolzano contains transcriptions of some early manuscripts which present his views in the*1810*'s on the foundations of logic, mathematics and physics. Bolzano's second book, Beyträge zu einer begründeteren Darstellung der Mathematik in*1810*, is a general introduction to the classification and methodology of mathematics. Most manuscripts of the present volume constitute steps toward the realization of a planned sequel to that book; their contents range from an exposition of General Mathesis, supplemented by an extensive analysis of the notion of quantity, through a theory of cause and consequence, called 'aetiology', to essays on geometry and mechanics. Among the other contributions, a manuscript on the basic concepts of logic adumbrates fundamental themes in Bolzano's major work, the Wissenschaftslehre of*1837*.* - Bernard Bolzano,
