H. P. Lovecraft said this quote

Man's respect for the imponderables varies according to his mental constitution and environment. Through certain modes of thought and training, it can be elevated tremendously, yet there is always a limit.

~ H. P. Lovecraft

Indeed, there is much in pure humanitarian culture, as opposed to rigid scientific training, which encourages absorption in the affairs of mankind, and more or less indifference to the unfathomed abysses of star-strown space that yawn interminably about this terrestrial grain of dust.

~ H. P. Lovecraft

We must realise that man's nature will remain the same so long as he remains man; that civilisation is but a slight coverlet beneath which the dominant beast sleeps lightly and ever ready to awake. To preserve civilisation, we must deal scientifically with the brute element, using only genuine biological principles.

~ H. P. Lovecraft

But more wonderful than the lore of old men and the lore of books is the secret lore of ocean.

~ H. P. Lovecraft
