We do not act because we know, but we know because we are called upon to act; the practical reason is the root of all reason.
Johann Gottlieb FichteHere below is not the land of happiness: I know it now; it is only the land of toil, and every joy which comes to us is only to strengthen us for some greater labor that is to succeed.
Johann Gottlieb FichteAll death in nature is birth, and at the moment of death appears visibly the rising of life. There is no dying principle in nature, for nature throughout is unmixed life, which, concealed behind the old, begins again and develops itself. Death as well as birth is simply in itself, in order to present itself ever more brightly and more like to itself.
Johann Gottlieb FichteHumanity may endure the loss of everything; all its possessions may be turned away without infringing its true dignity - all but the possibility of improvement.
