Conditioned. The Unconditioned, though it exists, is not 

 an object of knowledge, not even to the extent that 

 Kant conceived it to be viz., as a limiting idea and

 governed the early development of Comte' s mind were 

 similar to those which made themselves felt in the case 

 of John Stuart Mill. Both had a precocious develop- 

 ment; the ideas attained in childhood, which in the 

 case of most, even of the great, thinkers are characterised
