Reality cannot be found except in One single source, because of the interconnection of all things with one another. I maintain also that substances, whether material or immaterial, cannot be conceived in their bare essence without any activity, activity being of the essence of substance in general.
Gottfried LeibnizTo love is to take delight in happiness of another, or, what amounts to the same thing, it is to account another's happiness as one's own.
Gottfried LeibnizNothing is more important than to see the sources of invention which are, in my opinion more interesting than the inventions themselves.
Gottfried LeibnizThere are also two kinds of truths, those of reasoning and those of fact. Truths of reasoning are necessary and their opposite is impossible, and those of fact are contingent and their opposite is possible. When a truth is necessary its reason can be found by analysis, resolving it into more simple ideas and truths until we reach those which are primitive.
