Non- Euclidean calculus and quantum physics are enough to stretch any brain; and when one mixes them with folklore, and tries to trace a strange background of multi-dimensional reality behind the ghoulish hints of Gothic tales and the wild whispers of the chimney-corner, one can hardly expect to be wholly free from mental tension. (Dreams In The Witch-House)

Something like fear chilled me as I sat there in the small hours alone-I say alone, for one who sits by a sleeper is indeed alone; perhaps more alone than he can realise.

An isolated person requires correspondence as a means of seeing his ideas as others see them, and thus guarding against the dogmatisms and extravagances of solitary and uncorrected speculation. No man can learn to reason and appraise from a mere perusal of the writing of others.
