say that knowledge is not to be valued for its own sake. The validity (_prâmâ@nya_) of anything consists in this, that it directly helps us to get what is good for us and to avoid what is bad for us. Knowledge alone has this capacity, for by it we can adapt ourselves to our environments and try to acquire what is good for us and avoid what is bad [Footnote ref 1]. The conditions that lead to the production of such knowledge (such as the presence of full light and proximity to the eye in the case of seeing an object by visual perception) have but little relevancy in this connection. For we are not concerned with how a cognition is produced, as it can be of no help to us in serving our purposes. It is enough for us to know that external objects under certain conditions assume such a special fitness (_yogyatâ_) that we can have knowledge of them. We have no guarantee that they generate knowledge in us, for we are only aware that under certain conditions we know a thing, whereas under other conditions we do not know it [Footnote ref 2]. The enquiry as to the nature of the special fitness of things which makes knowledge of them possible does not concern us. Those conditions which confer such a special fitness on things as to render them perceivable have but little to do with us; for our purposes which consist only in the acquirement of good and avoidance of evil, can only be served by knowledge and not by those conditions of external objects. Knowledge reveals our own self as a knowing subject as well as the objects that are known by us. We have no reason to suppose (like the Buddhists) that all knowledge by perception of external objects is in the first instance indefinite and indeterminate, and that all our determinate notions of form, colour, size and other characteristics of the thing are not directly given in our perceptual experience, but are derived only by imagination (_utprek@sâ_), and that therefore true perceptual knowledge only certifies the validity of the indefinite and indeterminate crude sense data (_nirvikalpa jñâna_). Experience shows that true knowledge on the one hand reveals us as subjects or knowers, and on the other hand gives a correct sketch of the external objects in all the diversity of their characteristics. It is for this reason that knowledge is our immediate and most prominent means of serving our purposes. __________________________________________________________________ [Footnote 1: _Pramâ@na-naya-tattvâlokâla@mkâra,_ p. 26.] [Footnote 2: See _Parî@sa-mukha-sûtra,_ II. 9, and its v@rtti, and also the concluding v@rtti of ch.
