“Apart from sex linkage, we know almost nothing at present of linkage in man. Yet it is certain that every defect determined by a single factor must be located in one or other of twenty-three [sic] linkage groups. Each defect must therefore be linked in inheritance with numerous other observable traits, and with some of them is probably linked closely. The search for such linkage will certainly be lengthy, and at first, disappointing.”

Context: If on the one hand the Scholastics and Alchemists seem to be utterly at variance, and the Eclectics on the other hand quite at one, yet, strictly examined, it is altogether the reverse. The former, in essentials, are indirectly of one opinion; namely, as regards the non-dependence, and infinite character of Meditation, they both set out from the Absolute: whilst the Eclectic and limited sort are essentially at variance; and agree only in what is deduced. The former are infinite but uniform, the latter bounded but multiform; the former have genius, the latter talent; those have Ideas, these have knacks (Handgriffe); those are heads without hands, these are hands without heads. The third stage is for the Artist, who can be at once implement and genius. He finds that that primitive Separation in the absolute Philosophical Activities' (between the Scholastic, and the "rude, intuitive Poet") 'is a deeper-lying Separation in his own Nature; which Separation indicates, by its existence as such, the possibility of being adjusted, of being joined: he finds that, heterogeneous as these Activities are, there is yet a faculty in him of passing from the one to the other, of changing his polarity at will. He discovers in them, therefore, necessary members of his spirit; he observes that both must be united in some common Principle. He infers that Eclecticism is nothing but the imperfect defective employment of this principle.
