To assist in the analysis of fear, and in the denunciation of its expressions, I have coined the word fearthought to stand for the unprofitable element of forethought, and have defined the word 'worry' as fearthought in contradistinction to forethought. I have also defined fearthought as the self-imposed or self-permitted suggestion of inferiority, in order to place it where it really belongs, in the category of harmful, unnecessary, and therefore not respectable things.
